Question 41

When you add sugar to it, your cup of coffee becomes not only sweet but also fattening.

The sentence is grammatically correct with the inclusion of "also," which properly connects the two adjectives describing the coffee. The word "also" is essential to indicate that the coffee is both sweet and fattening.

A) to

The word "to" does not enhance the grammatical structure of the sentence. It serves as a preposition but does not contribute to the parallelism required between the two qualities attributed to the coffee.

B) becomes

The verb "becomes" is already correctly placed in the sentence, indicating a transition in the state of the coffee. However, it does not address the need for a coordinating conjunction that would create a parallel structure.

C) also

The word "also" is crucial for the sentence's structure, as it creates a parallel relationship between the two adjectives "sweet" and "fattening." Without "also," the sentence fails to convey that both qualities apply simultaneously to the coffee.

D) cup of

The phrase "cup of" is necessary for identifying what is being discussed, but it does not contribute to the grammatical correctness of the parallel structure in the sentence. Removing it would lead to ambiguity regarding the subject.

Conclusion

The use of "also" is critical for maintaining the grammatical coherence of the sentence by linking the two descriptive qualities of the coffee. While other options serve different functions within the sentence, they do not fulfill the necessary role of establishing a parallel structure. Thus, "also" is the definitive choice for making the sentence correct.
