Sentence Correction: Parts of Speech - Adverbs

Scientists have discovered new ways of integrating segmented nanorods and quantum dots into a variety of branching forms and have applied new techniques to precise calculate the electronic properties of these nanostructures, whose dimensions are measured in billionths of a meter.

Incorrect.

Although this answer choice corrects the original grammatical error by changing the adjective precise to the adverb precisely so that the adverb properly describes the verb calculate, it is stylistically flawed. The phrase properties that are electronic is awkward and creates wordiness.

Incorrect.

Although this answer choice corrects the original grammatical error by changing the adjective precise to the adverb precisely so that the adverb properly describes the verb calculate, it changes the meaning of the original sentence.

The full sentence in this answer choice now reads: have applied new techniques of these nanostructures - in the original sentence, the techniques were for calculating, they did not belong to the nanostructures. 

Make sure you read each answer choice along with the original sentence.

Incorrect.

This answer choice is grammatically incorrect and repeats the original mistake. An adverb should be used to describe a verb. In this sentence, an adjective (precise) is used to describe a verb (calculate).
