Understanding the Correct Answer: "might"
In the sentence "We __________ take a detour before we reach the destination," the correct option is "might." Let's explore why this is the case.

Possibility and Uncertainty
- The word "might" expresses a possibility or uncertainty about an action.
- Using "might" suggests that taking a detour is not guaranteed but is a potential option under certain circumstances.

Comparison with Other Options
- **would**: This implies a strong intention or willingness to take the detour. However, it doesn't convey uncertainty, which is essential in this context.
- **should**: This indicates a recommendation or obligation. It implies that taking a detour is advisable, but again, it lacks the element of possibility.
- **will**: This word suggests a definite future action. It indicates certainty, which does not fit the context of the sentence as it is about an uncertain situation.

Contextual Relevance
- The sentence hints at an option rather than a commitment. Therefore, "might" is the most suitable choice.
- It leaves room for other possibilities, acknowledging that a detour may or may not occur.

Conclusion
In summary, "might" is the best answer because it encapsulates the idea of a potential detour without asserting any certainty or obligation. It perfectly fits the context of the sentence, making it the correct choice.

Explanation:
To determine the correct answer, we need to consider the meaning and context of the sentence.
- The sentence states, "We __________ take a detour before we reach the destination."
- The word "detour" suggests a deviation from the usual or direct route to the destination.
- Based on this context, we can eliminate options A ("would") and D ("will") because they indicate a certain or definite action, implying that a detour is already planned or decided upon.
Now let's consider the remaining options:
B:

should

- "Should" suggests a recommendation or advice.
- It implies that taking a detour is a sensible or appropriate course of action.
- However, the sentence doesn't provide any information to support this recommendation, so we cannot determine if it is the correct answer.
C:

might

- "Might" suggests a possibility or uncertainty.
- It implies that taking a detour is one of the potential options, but it is not confirmed or guaranteed.
- This aligns with the context of the sentence, as it leaves open the possibility of either taking a detour or continuing on the direct route.
Therefore, based on the given sentence and the meaning of the options, the correct answer is C: "might."
