Question

Fill in the blank with the correct option : 
It rained _____ three days without stopping.

Accepted Answer

The sentence in question is: "It rained _____ three days without stopping." The task is to fill in the blank with the correct option, and the correct answer is Option 2: "for."

1. **Explanation for Option 2 ("for"):**
   - The preposition "for" is used to indicate a period of time during which an action occurs. In this sentence, "for" appropriately describes the duration of the rain, which lasted three days. The phrase "for three days" effectively communicates that the rain continued without interruption over the specified time period. This usage is standard in English when expressing how long something lasts.

2. **Explanation for why the other options are incorrect:**

- **Option 1 ("during"):**
     - "During" is used to indicate a time frame in which something happens, but it is typically followed by a noun that represents an event or a specific period, such as "during the meeting" or "during the summer." It does not fit well with a specific duration like "three days" without an accompanying event or period.

- **Option 3 ("at"):**
     - "At" is used to specify a particular point in time, such as "at noon" or "at 5 PM." It is not suitable for expressing a duration of time, such as "three days." Therefore, it does not fit the context of the sentence, which requires indicating how long the rain lasted.

- **Option 4 ("while"):**
     - "While" is a conjunction used to indicate that two actions are happening at the same time, such as "while I was cooking, the phone rang." It is not used to express a duration of time by itself. In this sentence, "while" would not correctly convey the continuous nature of the rain over the three-day period.

In conclusion, Option 2 ("for") is the correct choice because it accurately describes the duration of the rain, aligning with standard English usage for expressing how long an action continues.
