Fill in the blank with the correct phrasal verb :
There is a mystery about his death and the police are _____ it.

Question

Accepted Answer

The correct phrasal verb to fill in the blank is "looking into" because it fits the context of a police investigation. Here's why:

*   **Looking into:** This phrasal verb means to investigate or examine something. In the context of a mysterious death, the police "looking into" it means they are investigating the circumstances surrounding the death to try and uncover the truth. This aligns perfectly with the sentence's meaning.

Now, let's explain why the other options are incorrect:

*   **Look out:** This means to be careful or vigilant. While caution might be involved in a police investigation, "look out" doesn't describe the *action* of investigating a mystery. It's more about warning someone of potential danger.

*   **Look ahead:** This means to think about the future. It has no relevance to investigating a past event like a death.

*   **Look after:** This means to take care of someone or something. This is completely unrelated to a police investigation into a death.

Therefore, "looking into" is the only phrasal verb that logically and grammatically fits the sentence, describing the police's action of investigating the mysterious death.
