Question

Accepted Answer

The phrase "looking into" is a common phrasal verb in English that means to investigate or examine something carefully. In the context of the sentence, "There is a mystery about his death and the police are looking into it," the police are conducting an investigation to uncover the details and circumstances surrounding the mysterious death. This aligns perfectly with Option 1: "To investigate," which is why it is the correct answer.

1. **Explanation for Option 1: To investigate**
   - The phrasal verb "looking into" is often used when someone is examining or investigating a matter to gather more information or to solve a problem. In this context, the police are trying to uncover the truth behind the mystery of the death, which involves gathering evidence, questioning witnesses, and analyzing information. This investigative process is precisely what "looking into" implies, making Option 1 the correct choice.

2. **Explanation for why other options are incorrect:**
   - **Option 2: To take care of**
     - "To take care of" generally means to look after someone or something, ensuring that it is safe or well-maintained. It does not imply an investigation or examination of a situation. Therefore, this option does not fit the context of the police examining a mystery.
   
   - **Option 3: To look behind**
     - "To look behind" suggests a physical action of turning one's head or body to see what is behind them. It does not relate to investigating or examining a situation. Thus, it is not applicable in the context of the police investigating a mystery.
   
   - **Option 4: To revise quickly**
     - "To revise quickly" implies reviewing or going over something, often in a hurried manner, such as studying for an exam. This does not involve the thorough and careful examination that "looking into" suggests in the context of a police investigation. Therefore, it is not the correct interpretation of the phrasal verb in this context.

In conclusion, the phrase "looking into" in the given sentence clearly means "to investigate," which is why Option 1 is the correct answer. The other options do not align with the meaning of the phrasal verb in this context.
