Fill in the blank with the word that best fits.The _______ valley opened up before us, seeming to extend beyond the horizon.abruptextremevastbrisk

To determine the best word to fill in the blank in the sentence, we need to analyze each option in relation to the context provided.

Analysis of Options:

1. Abrupt: This adjective typically describes something sudden or unexpected. It doesn’t fit well with the context of a valley that seems to extend beyond the horizon.

2. Extreme: While “extreme” could describe something that is very intense or beyond the usual limits, it doesn’t cohesively connect with “valley” in a way that would effectively convey the visual image of vastness.

3. Vast: This adjective means very great in extent or quantity, which directly corresponds with the description of something that seems to extend far into the horizon.

4. Brisk: Generally describes something quick, energetic, or chilly. It is not relevant when describing a valley.

Conclusion:

Given the context of the sentence and the meanings of the options, the word “vast” is the most appropriate choice. This is because it encapsulates the sense of a large, open area that aligns well with the imagery of a valley extending into the horizon.

Final Answer:

The vast valley opened up before us, seeming to extend beyond the horizon.
