Question

15 mark for review which choice completes the text so that it conforms to the conventions of standard english? interested in mechanotransduction, the mechanism by which cells sense and convert mechanical stimuli into biochemical signals, is expanding because of innovative work by biomedical scientists—many of whom, like neuroscience and biophysics expert elba herrera, ______ this mechanism to better understand how the body’s neurological and biochemical systems interact. a is studying b has studied c study d studies

Explanation:

The sentence structure here requires a verb form that fits the context of Elba (a singular subject) performing an action related to studying the mechanism. The simple present tense "studies" (option D) is appropriate as it shows a habitual or ongoing action in the present, and "Elba" is a third - person singular subject, so the verb should be in the third - person singular form of the simple present. "Is studying" (A) is present continuous, which may not fit the general context of her work. "Has studied" (B) is present perfect, which is used for actions with a connection to the present but the context here is more about her general action of studying. "Study" (C) is the base form and does not agree with the third - person singular subject.

Answer:

D. studies
