The area is ___ close circuit television survey.

Question: The area is ___ close circuit television Correct Answer: B. under

The correct answer is 'under' because it appropriately matches the prepositional usage with the noun phrase 'close circuit television survey' in English.

Here is a detailed explanation for each option:

• into: This preposition suggests movement or direction towards the inside of something. It is not suitable here because the sentence refers to a state of being monitored or observed rather than moving into something. Example: "She went into the house."

• under: This preposition is the most appropriate as it indicates being subject to a condition, authority, regulation, or surveillance. In this context, the area is under surveillance by CCTV, meaning it is being monitored. Example: "The project is under review."

• over: This preposition is used to indicate movement or position above something. It doesn't fit in this context as it does not convey the idea of being within the scope of surveillance. Example: "The cat jumped over the fence."

• about: This preposition would indicate a topic or subject matter but does not convey the concept of being surveilled or monitored. Example: "We had a discussion about the new policy."

Thus, 'under' is the correct preposition to use in the context of surveillance, which is why the correct answer is 'under'. For more on the appropriate use of prepositions, you can refer to resources like the Grammarly Blog or Purdue OWL.
