Directions: The following sentence has been split into four parts (A), (B), (C) and (D). If there is any grammatical error in any of these parts, that is the answer. If there is no error, the answer is (E).

The engineer was told (A)/ to calculate the (B)/ measurements carefully, accurately (C)/ and with precision. (D)/ No error (E)

This is the correct option as this part of the sentence has the error of parallelism. In this sentence, 'carefully' and 'accurately' are both adjectives, but 'with precision' is not. The correct sentence will replace 'with precision' with 'precisely'. Thus, the correct sentence will be: The engineer was told to calculate the measurements carefully, accurately and precisely.
