• In English grammar, certain adjectives are followed by specific prepositions. This is known as a prepositional colocation.
• The word 'faithful' is always followed by the preposition 'to' when referring to a person, a cause, or a responsibility.
• The other options 'on', 'by', and 'over' do not grammatically pair with 'faithful' in this context.

Therefore, the correct answer is Option 4.

 

Complete Sentence: 'An employee should be faithful to his duty.'

 

Additional Information

• Prepositional Phrases: Other adjectives that commonly use 'to' include 'loyal to', 'dedicated to', and 'committed to'.
• Example: He has always been faithful to his principles throughout his career.

The correct answer is Are the stars studied by the astronomers through powerful telescopes?.

Key Points

• The original sentence 'Do the astronomers study the stars through powerful telescopes?' is an Interrogative Sentence written in the Simple Present Tense.
• To convert an interrogative sentence in the Simple Present from Active Voice to Passive Voice, the auxiliary verbs 'Do/Does' are replaced by 'Is/Am/Are' depending on the number and person of the new subject.
• In this sentence, the Active Subject is 'the astronomers' and the Active Object is 'the stars'. In the passive form, 'the stars' becomes the Passive Subject.
• Since 'the stars' is a plural noun, the sentence must begin with the plural auxiliary verb 'Are' to maintain Subject-Verb Agreement.
• The main verb 'study' must be transformed into its Past Participle form (V3), which is 'studied'.
• The phrase 'by the astronomers' is added to indicate the agent performing the action, followed by the remaining prepositional phrase 'through powerful telescopes' which acts as an adjunct.
• The basic structure followed is: Are + Passive Subject (the stars) + Past Participle (studied) + by + Agent (the astronomers) + ...?

 Additional Information

• Understanding why other variations are grammatically incorrect for this specific conversion:
• Present Continuous Passive: Sentences including 'being studied' belong to the Present Continuous Tense. This structure is used for actions currently in progress, which does not match the Simple Present nature of the original query.
• Present Perfect Passive: The use of 'Have... been studied' shifts the tense to the Present Perfect. This tense describes actions completed at an unspecified time before now, changing the original meaning of a general or habitual inquiry.
• Singular vs. Plural Agreement: Using the auxiliary verb 'Is' with the singular noun 'star' is a grammatical mismatch when the original sentence explicitly refers to plural 'stars'.
• Voice Transformation Rule: The primary objective in Voice conversion is to ensure the Tense remains constant while the focus shifts from the doer to the receiver of the action.

The correct answer is The teacher had provided a detailed explanation before the students attempted the experiment..

Key Points

• The original sentence is in the Passive Voice and utilizes the Past Perfect Tense, as evidenced by the construction had been + past participle (provided).
• When converting from Passive to Active Voice in the Past Perfect Tense, the structural formula follows: Subject + had + V3 (Past Participle) + Object.
• In this transformation, the agent of the action in the passive sentence, the teacher, transitions to the subject position to perform the action directly.
• The grammatical object of the passive sentence, a detailed explanation, becomes the direct object in the active sentence, receiving the action of the verb.
• The auxiliary verb been is strictly removed during the conversion to Active Voice, while the primary auxiliary had is retained to maintain the Past Perfect aspect.
• The subordinate clause before the students attempted the experiment serves as a temporal marker and remains unchanged, as it is already in the Active Voice and describes a subsequent past action.
• Linguistic rules for Past Perfect require the first completed action in a sequence of two past events to be expressed using the had + V3 format.

 Additional Information

• Understanding Tense Consistency in Voice Change:
• Simple Past Tense: Converting to The teacher provided would represent a Simple Past construction (Subject + V2). This is incorrect as it fails to preserve the Perfect aspect of the original sentence.
• Simple Present Tense: The use of provides indicates a habitual or current action. This is logically and grammatically inconsistent with the past-tense context established by attempted.
• Past Continuous Tense: The phrase was providing suggests an ongoing action (Subject + was/were + V-ing). The original passive sentence implies a completed action (had been provided), making the continuous form an inaccurate conversion.
• Past Perfect Significance: This tense is vital in English Grammar for establishing the Past-in-the-Past, ensuring the sequence of events is clear to the reader.

The correct answer is Arrange the books neatly on the shelf..

Key Points

• The provided sentence 'Let the books be arranged neatly on the shelf' is in the passive voice, which follows the specific imperative mood structure used for commands, requests, or suggestions.
• In English grammar, a passive imperative sentence often utilizes the formula: Let + Object + be + Past Participle (V3). In this instance, 'the books' serves as the object and 'arranged' is the V3 form of the verb.
• To transform this into the active voice, the sentence must be converted into a direct imperative sentence, which begins with the base form of the verb (V1).
• The structural pattern for an active imperative sentence is Verb (Base Form) + Object + Adverbial/Complement. Consequently, the verb 'arrange' is placed at the start, followed by the object 'the books'.
• In such active constructions, the second-person pronoun 'You' is the implied subject, although it is traditionally omitted for brevity and directness.

 Additional Information

• Voice Transformation Rules:
• When shifting from passive to active voice in imperative sentences, the introductory word 'Let' and the auxiliary verb 'be' are discarded.
• The past participle (arranged) must revert to its present tense base form (arrange) to initiate the command.
• The phrase 'neatly on the shelf' remains unchanged as it functions as an adverbial of manner and place, providing necessary context to the action.
• Conceptual Clarity on Options:
• Options involving 'You let arrange' or 'You must let' change the original intent of the sentence from a simple command to a permission or a high-modality obligation, which does not accurately reflect a standard voice conversion.
• Active voice is preferred in instructional writing and manuals for its clarity and economical use of words.

The correct answer is Option 3.

 

Key Points

• The error is in the third part of the sentence: 'came in the room crying and complained.'
• The primary grammatical mistake is the use of the preposition 'in' instead of 'into.'
• The preposition 'in' usually denotes a state of being inside or a position within a space. In contrast, 'into' is used to indicate movement, motion, or entry toward the inside of a place.
• Since Rosemerry is moving from the garden to the inside of the room, the phrase should correctly be 'came into the room.'
• Thus, Option 3 contains the error.

Therefore, the correct answer is came in the room crying and complained.

 

Correct Sentence: 'Rosemerry did not see the beautiful roses in the garden and came into the room crying and complained that the roses had lost their fragrance.'

 

Additional Information

• 'Rosemerry did not see the beautiful' – This part uses the correct simple past negative structure (did + not + base verb).
• 'roses in the garden and' – This part is grammatically sound, using 'in' correctly to show the location of the roses.
• 'that the roses had lost their fragrance.' – This part correctly uses the past perfect tense ('had lost') to indicate an action that happened before she complained.
• Parallelism: The verbs 'came' and 'complained' are both in the simple past tense, maintaining consistency in the sentence structure.

The correct answer is 'on'.

 

Key Points

• The phrasal verb 'call on' means to pay a visit to someone or to formally ask someone to do something or to speak.
• In the given sentence, the members are deciding to visit the MLA (Member of Legislative Assembly), making 'on' the grammatically appropriate preposition to form the correct phrasal verb.
• Options 1, 2, and 3 do not convey the intended meaning of visiting a person in this context.

Therefore, the correct answer is Option 4.

 

Complete Sentence: 'The club members decided to call on the MLA.'

 

Additional Information

• Option 1: 'with' is not part of a standard phrasal verb with 'call' that implies visiting or demanding.
• Option 2: 'call for' means to demand or require something (e.g., 'The situation calls for immediate action').
• Option 3: 'call at' means to briefly stop at a place, usually said of a train, ship, or person visiting a house (e.g., 'The train calls at every station').

The correct answer is Option 1.

 

Key Points

• The sentence requires a mixed conditional structure. This specific type of mixed conditional is used to describe a past condition that has a present result.
• The formula for this mixed conditional is: If + Past Perfect (subject + had + past participle), would + base verb (present result).
• The use of the word 'now' in the second part of the sentence ('you would be lost now') signifies that the result is in the present. Therefore, the condition that led to this state must be in the past.
• The original phrase 'If you asked' uses the Past Simple, which is typically for hypothetical present/future situations (Second Conditional). To reflect a past action, it must be changed to 'If you had asked'.

Therefore, the correct answer is Option 1.

 

Correct Sentence: 'If you had asked for directions at the petrol pump, you would be lost now.'

 

Additional Information

• Option 2: If you would have asked for directions – This is grammatically incorrect. In conditional sentences, 'would' or 'would have' should never be used in the 'if' clause.
• Option 3: If you ask for directions – This uses the Present Simple tense, which is used in first conditionals for real possibilities. It does not match the hypothetical result 'would be'.
• Option 4: No improvement required – This is incorrect because the original sentence uses the Second Conditional (Past Simple in the if-clause), which generally refers to a hypothetical present. The context here strongly suggests a past-to-present relationship, making the Mixed Conditional more appropriate.

The correct answer is Option 2.

 

Key Points

• According to the first sentence of the passage, nuclear activities generate approximately 200,000 m³ of radioactive waste every year.
• The text distinguishes between the total amount of waste produced (200,000 m³) and the portion that contains most of the radioactivity (10,000 m³).
• The question specifically asks for the amount generated annually (every year), which corresponds directly to the figure 200,000 m³.
• Therefore, the correct figure for annual generation is Option 2.

Therefore, the correct answer is Around 200,000 m³.

 

Correct Sentence: "Nuclear activities generate around 200,000 m³ of radioactive waste every year."

 

Additional Information

• Around 10,000 m³: This refers to the specific volume of waste that contains the highest radioactivity and requires storage in Geological Disposal Facilities (GDFs).
• Geological Disposal Facilities (GDFs): These are purpose-built caverns located hundreds of meters underground to safely store hazardous waste.
• Waste Management: The passage highlights that while a large volume is produced, only a fraction requires deep, long-term geological storage.

The correct answer is Option 1.

 

Key Points

• The passage states that a specific cement formulation called CEBAMA is being considered for Geological Disposal Facilities (GDFs) in Europe.
• One of the primary advantages of CEBAMA is its lower pH level compared to standard cement.
• According to the text, a lower pH is highly desirable because alkaline water (which has a high pH) has the potential to corrode steel.
• Since the radioactive waste is packed into steel containers, preventing or reducing corrosion is essential for the long-term safety and stability of the storage facility.

Therefore, the correct answer is 1.

 

Additional Information

• Geological Disposal Facilities (GDFs) are engineered tunnels and caverns built hundreds of meters underground to isolate highly radioactive waste from the environment.
• Cement serves multiple roles in a GDF, including supporting tunnels, holding waste in place, and acting as a barrier to slow the movement of radioactive materials.
• While CEBAMA shows promise due to its chemical compatibility, researchers are still investigating how its chemical and structural properties will evolve over the many centuries required for storage.

The correct answer is Option 2.

 

Key Points

• According to the passage, cement plays a crucial structural and protective role in Geological Disposal Facilities (GDFs).
• The text explicitly states that in these facilities, cement is used to hold waste in place and support tunnels.
• Furthermore, it serves as a barrier that helps slow the movement of radioactive material in the event that groundwater enters the facility.
• Therefore, the primary purpose of the cement backfill is to ensure the stability of the waste and mitigate the risk of environmental contamination.

Therefore, the correct answer is To hold waste in place and slow the movement of radioactive material.

 

Additional Information

• Geological Disposal Facilities (GDFs) are specialized caverns built hundreds of meters underground to store highly radioactive waste for the long term.
• Modern formulations like CEBAMA are being developed with a lower pH to prevent the corrosion of steel waste containers, which can occur in highly alkaline environments.
• The facility design typically involves a combination of waste containers, cement backfill, and natural barriers like clay host rock to ensure safety over thousands of years.

The correct answer is Option 3.

 

Key Points

• According to the passage, CEBAMA is a candidate for Europe's Geological Disposal Facilities (GDFs) due to its lower pH and favorable structural performance.
• However, the final sentence of the passage highlights a significant uncertainty: 'there are important questions about how CEBAMA will evolve over the centuries.'
• This evolution specifically refers to the potential chemical and structural changes the cement might undergo over long periods under high pressure and geological conditions.
• Therefore, the remaining concern identified is its evolution chemically and structurally.

Therefore, the correct answer is Option 3.

 

Correct Sentence: "The remaining concern about CEBAMA cement in GDFs is its evolution chemically and structurally over the centuries."

 

Additional Information

• Whether it can block radiation for millennia: While radiation shielding is a general goal of GDFs, the passage specifically points to the evolutionary stability of the cement as the primary remaining question.
• Its potential to fully replace steel containers: The text mentions that cement holds waste in place and reduces corrosion of steel containers, but it does not suggest that cement is intended to replace them.
• Its cost relative to the current cement option: The passage focuses on technical, chemical, and structural aspects; cost or economic feasibility is not mentioned as a concern.

The correct answer is Option 4.

 

Key Points

• According to the passage, nuclear activities generate a significant amount of waste, but the most hazardous portion (about 10,000 m³) requires deep, long-term geological storage.
• Geological Disposal Facilities (GDFs) are specifically designed as caverns built hundreds of meters underground to house this radioactive waste.
• The primary function of a GDF is to provide a secure environment where waste containers and cement backfill work together with host rock to isolate hazardous materials from the biosphere.
• The text explicitly links the need for long-term storage of high-activity waste directly to the purpose of these underground facilities.

Therefore, the correct answer is To store highly radioactive waste deep underground.

 

Additional Information

• Recycling nuclear waste: While some nuclear technologies allow for recycling, the passage focuses exclusively on the disposal and storage aspects of waste management.
• Neutralizing radiation: The purpose of GDFs is containment and slowing the movement of radioactive material, not neutralizing the radioactivity through chemical treatments.
• International transport: The passage describes the structural components and geological requirements of the facilities rather than the transportation protocols across borders.
