The correct answer is 'CBDA'.

 Key Points

• The task in this question is to find the most logical order of the sentences that can form a coherent paragraph.
• Option 1, 'CBDA', is the right choice. Here's how the sentences fit together logically:
• C: 'Carol looked through the window into the first-class area.' – This sentence introduces the situation and the main character, Carol.
• B: 'There were many families relaxing on that Sunday afternoon.' – This sentence adds detail to the setting that Carol is observing.
• D: 'Children were splashing about the pool and many were sunbathing or snoozing on easy chairs.' – This sentence provides more specific observations about the setting that Carol is witnessing.
• A: 'However, Carol was not feeling well.' – This sentence presents a contrast to the relaxing and enjoyable scenes Carol is observing. It adds an emotional dimension to the paragraph, giving it a more comprehensive narrative scope.
• The other options are less logical. For example, if the paragraph starts with A (as in options 2 and 4), there's no context yet for Carol's illness. If it starts with D (as in option 3), it jumps directly into specific details without introducing the overall scene on the special Sunday.

Therefore, the correct answer is Option 1.

• S: 'The Cuban Missile Crisis was a 13-day confrontation between the United States and the Soviet Union.' - This sentence introduces the topic and provides a summary, good for a starting point.
• R: 'It was initiated by the American discovery of ballistic missile deployment in Cuba by the Soviet Union.' - This sentence logically follows S, providing more context of how the Cuban Missile Crisis began.
• P: 'The confrontation is often considered the closest the Cold War came to be escalated into a full-scale nuclear war.' - This sentence explains the gravity of the situation following the crucial occurrence described in R.
• Q: 'After several days of tense negotiations, an agreement was reached between John F. Kennedy and Khrushchev to ease the tensions.' - This sentence concludes the narrative, showing the resolution of the Cuban Missile Crisis.

• Rhizobium bacteria fixes the nitrogen present in the air which is required by the leguminous plant while the plant provides the bacteria with sugars in return.
• Rhizobia are soil bacteria that fix nitrogen after becoming established inside root nodules of legumes. In order to express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen.

Important Points

• Rhizobia, a type of nitrogen-fixing soil bacterium, can create a symbiotic association with legumes.
• This symbiosis results in the formation of nodules on the plant root, within which the bacteria may convert air nitrogen into ammonia, which the plant can use.
• The establishment of a successful symbiosis necessitates the compatibility of the two symbiotic partners throughout the symbiotic development phase.
• However, incompatibility commonly arises, resulting in a bacterial strain's inability to nodulate a certain host plant or the formation of nitrogen-fixing nodules.
• Rhizobia are nitrogen-fixing diazotrophic bacteria that develop themselves inside the root nodules of legumes.
• Rhizobia need a plant host to express genes for nitrogen fixation; they can't fix nitrogen on their own.
