The correct answer is: E. No error
The sentence is grammatically correct. The word “ever since” is used to introduce a clause that expresses a time relationship. In this case, the clause “ever since the government announced its new policy” expresses the time at which the private institutions began to run into heavy weather. The word “had” is used to form the past perfect tense, which is used to express an action that was completed before a certain time in the past. In this case, the action of the private institutions running into heavy weather was completed before the time at which the government announced its new policy. The word “run into” is a phrasal verb that means “to experience difficulties.” In this case,
the private institutions experienced difficulties after the government announced its new policy.The other options are incorrect because they contain grammatical errors. Option A is incorrect because the word “ever” should not be
used with the word “since.” Option B is incorrect because the word “announced” should be followed by a noun or pronoun. Option C is incorrect because the word “had” should not be used with the word “run.” Option D is incorrect because the word “run” should be followed by a noun or pronoun.
