10. Select the word or phrase that makes this sentence grammatically correct: The child's fever was too high for him to lie comfortably in bed.

Answer: C

Explanation:

The child's fever was too high for him to lie comfortably in bed.

Using "too" in this context indicates that the fever is excessively high, preventing the child from lying comfortably in bed.

A) to

The word "to" does not convey the necessary meaning in this sentence. It does not indicate the degree of the fever's severity, which is essential to understanding why the child cannot lie comfortably.

B) much

The use of "much" would be grammatically incorrect in this context. While "much" can indicate a large amount, it does not appropriately describe the extent of the fever in relation to the child's comfort in bed.

C) too

Using "too" correctly expresses that the fever is excessively high, which directly affects the child’s ability to lie comfortably in bed. This choice accurately reflects the intended meaning of the sentence.

D) more

The word "more" does not fit within the context of the sentence. It implies a comparative increase rather than indicating an excessive level, which is critical for understanding the child's discomfort.

Conclusion

The choice "too" is definitively correct as it effectively communicates the excessive nature of the fever, which is crucial for explaining the child's inability to lie comfortably. In contrast, the other options fail to convey this essential meaning, making them incorrect for the sentence's context.
