Answer» The error lies in the II part of the SENTENCE. ‘Has been PERMITTING’ is wrong since it is in the present perfect continuous tense. The present perfect continuous tense which shows that something started in the past and is continuing at the present time. The present perfect continuous is formed using the construction has/have been + the present PARTICIPLE (root + -ing). The correct tense to be used is simple present, since the structure of the sentence is in simple present. Hence the verb should be ‘PERMITS’. Hence the correct answer is option 4. Correct sentence: Sometimes developmentalists use a procedure called meta-analysis, which permits COMBINING the results of many studies into one overall conclusion. |
