51. Select the meaning of the underlined word in this sentence. Which word means to place under *observation*?
Answer: A
Surveillance
The word that means to place under observation is "surveillance." This term specifically refers to the act of closely monitoring or watching someone or something, often for purposes of security or evaluation.
A) Surveillance
Surveillance is the correct answer as it directly relates to the act of observing or monitoring individuals or situations. It is commonly used in contexts involving security, law enforcement, and research, where observation is key to gathering information.
B) Cogitation
Cogitation refers to the act of thinking deeply or contemplating. While it involves mental observation, it does not denote the act of placing someone or something under observation in a physical or monitoring sense, making it an incorrect choice.
C) Assessment
Assessment implies evaluating or appraising something based on observation or analysis. However, it does not specifically mean to place something under observation; instead, it focuses on the outcome of that observation, thus rendering it incorrect.
D) Isolation
Isolation means to separate or set apart from others. It does not relate to the act of observation and instead suggests a lack of observation or connection, making this option incorrect in the context of the question.
Conclusion
Surveillance is definitively the right choice as it encapsulates the essence of placing someone or something under observation. The other options—cogitation, assessment, and isolation—fail to convey the direct action of observing, thereby confirming that they are not suitable alternatives.
