Terming the recent spate of cyberattacks a wake-up call
for tech companies as well as governments, Mr. Smith said the world was more secure when networks ran in the cloud as opposed to servers. In each question below, a sentence is given with a part of it printed in bold type. That part may contain a grammatical error. Each sentence is followed by phrases 1), 2), 3) and 4). Find out which phrase should replace the phrase given in bold to correct the error, if there is any, and to make the sentence grammatically meaningful and correct. If the sentence is correct as it is and ‘No correction is required’, mark 5) as the answer.Solution
The phrase in the question is correct. The word ‘spate’ means ‘a large number of similar things coming in quick succession’. In A, ‘among’ is not appropriate. In B, ‘wake up call in companies’ is not correct. ‘Unless’ is unnecessary in C. ‘Termed’ in D will make the sentence grammatically incorrect.
