Answer 1

The grammatically correct version of the sentence is 'The blue hyacinth macaw feeds on a diet of Brazil nuts,' which requires no change from option a). The other options add unnecessary punctuation or articles, altering the original grammatically correct sentence.

Step-by-step explanation:

The correct grammatical form of the underlined portion of the sentence, 'The blue hyacinth macaw feeds on a diet of Brazil nuts, crushing the nuts' shells in its powerful beak,' is option a) No change. This sentence correctly states the subject, 'The blue hyacinth macaw,' followed by the verb 'feeds' and the phrase describing its diet. The other options, b), c), and d), introduce unnecessary punctuations such as commas and article changes that are not grammatically required.
