• Sentence S6 is the conclusion of the story, where Kabir declares himself Ramananda's disciple.
• Therefore, the correct answer is option 4.

The correct answer is option 2.

Key Points

• The sentence contains an error in the part "changed the leadership of it's legal" of the sentence.
• The error is the incorrect use of the contraction "it's" instead of the possessive pronoun "its". "It's" is a contraction for "it is" or "it has", while "its" is a possessive pronoun indicating possession or belonging.
• So, "it's" should be replaced with "its".
• Therefore option 2 is correct.

Correct sentence: Over the past year, the company has changed the leadership of its legal, policy, and communications teams.

• Sentence A contrasts the situation in the east with the progress made by the Allied Forces in the west, completing the paragraph's overview of the military situation in June 1944.
• Therefore the correct answer is option 1.

The correct answer is Green energy 

Key PointsGreen energy: This option refers to renewable energy sources that are environmentally friendly and sustainable. Green energy includes wind energy, solar energy, hydropower, biomass, and other forms of renewable energy that have minimal environmental impact compared to fossil fuels. These sources produce electricity without emitting greenhouse gases or other pollutants that contribute to air and water pollution or climate change. 

Wind energy & green energy: Both wind energy and other forms of renewable or "green" energy sources, such as solar energy, hydropower, and biomass, are considered environmentally friendly.Wind energy is considered a form of green energy or renewable energy. Wind energy harnesses the kinetic energy of wind to generate electricity through wind turbines, while green energy encompasses various renewable energy technologies that utilize natural resources in sustainable ways.

Green energy: This option refers to renewable energy sources that are environmentally friendly and sustainable. Green energy includes wind energy, solar energy, hydropower, biomass, and other forms of renewable energy that have minimal environmental impact compared to fossil fuels.

Solar energy: Solar energy, derived from sunlight, is also a clean and renewable energy source. Solar panels convert sunlight into electricity without emitting greenhouse gases or pollutants. Solar energy is abundant, widely available, and can be harnessed using photovoltaic cells or solar thermal systems.

Wind energy: Wind energy, generated from the movement of air masses, is another clean and renewable energy source. Wind turbines convert the kinetic energy of wind into electricity, providing a sustainable alternative to fossil fuels. Wind energy is abundant and can be harnessed both onshore and offshore.

In summary, Green energy, such as solar energy, are considered best for keeping the environment clean because they produce electricity without emitting harmful pollutants or greenhouse gases. These renewable energy sources play a crucial role in reducing carbon emissions, mitigating climate change, and promoting environmental sustainability.

The correct answer is Corona.

Key Points

• Corona is the outermost layer of the Sun.
• It experiences a very high temperature, about one million degrees Celcius.
• It starts at about 2100 km above the photosphere.
• Corona isn't visible from the earth (except during solar eclipse).
• The corona does not have an upper limit.
• Photosphere, the Chromosphere, the Transition Region, and the Corona are the outer layers of the sun.

Additional Information

The correct answer is Grass → Insects → Frog → Snake → Eagle.

Key Points

• Foodchain:
• ​The sequence of living organisms in a community in which one organism consumes another organism to transfer food energy is called a food chain.
• In simple words, a list of organisms showing 'who eats whom' is called the food chain.
• The food can be transferred from one organism to the other through the food chain.
• All food chains begin with green plants which are the source of all food.
• It represents a unidirectional transfer of energy.
• Example: eagle → snake → frog → insects → grass
• Each step in the food chain is called a trophic level.
• A food chain starts with producers and ends with top carnivores.
• Grass → Insects → Frog → Snake → Eagle
• Here grass is eaten by insects, insects are eaten by a frog, a frog is then eaten by a snake finally, a snake is eaten by an eagle.
• This completes a food chain.

The correct answer is 20 Hz to 20,000 Hz.

Key Points

Frequency: The number of waves that pass a fixed point in unit time.

The unit of frequency is Hertz (Hz).

• Infrasonic sounds have a frequency of less than 20 Hz and these are generally produced by sources of a bigger size such as earthquakes, volcanic eruptions, etc.
• Sound waves with frequencies below the audible range are called infrasonic.
• Audible sounds have the frequency of 20-20000 Hz since these are sensitive to the human ears
• And if the frequency is greater or less than audible frequency, the human ear won't be able to sense it
• Ultrasonic sounds have a frequency greater than 20000 Hz and certain creatures such as dogs, cats, bats can hear this kind of sound.

So, human can hear from 20 Hz to 20000 Hz.

The correct answer is Cement.

Key Points 

• Limestone is a form of calcium carbonate which is used extensively for the manufacture of cement.
• Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminium, iron and other ingredients.
• Crushed limestone is often the main raw ingredient in the manufacture of portland cement.
• CaCO3 is the chemical formula of Calcium carbonate.
• Limestone is a carbonate sedimentary rock composed primarily of calcium carbonate (CaCO3).
• Limestone released carbon dioxide gas while heating.

Important Points 

• Limestone is used as:
• Building material.
• Essential component cement industry.
• Aggregate for the base of roads.
• Filler in products such as toothpaste or paints.
