Question
In the question given below, a sentence is given,
divided into parts. One of the parts may contain an error. Identify the part that contains the error, and mark it as the answer. Ignore errors of punctuation. In case the sentence is correct as it is, mark option (e), that is, 'No error'. Once docked, ISRO began tests to verify if the satellites could exchange electric power, then undock and separate, followed by testing their own payloads that would spread over two years.Solution
In the sentence, "spread" should be replaced with "be spread" because we need the verb to be in the passive form to match the context of "payloads" being the subject of the action. The sentence would then read: "Once docked, ISRO began tests to verify if the satellites could exchange electric power, then undock and separate, followed by testing their own payloads that would be spread over two years."
