Select the most appropriate option to substitute the emboldened segment in the given sentence. If no substitution is required, select "No Improvement".
The workers of this textile factory demand higher wages for a long time.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. have been demanding higher wages.
Explanation:
- The phrase "for a long time" indicates the duration of some activity that started in past and still continues.
- We use present/past perfect continuous to represent such actions.
- The underlined phrase is in simple present tense; hence, is incorrect and we can say that the sentence needs improvement.
- Only option 1 is in present perfect continuous tense as it holds the structure ‘have + been + verb + ing’.
- Option 2 is simple past while option 4 is present perfect.
Hence, the chosen option is correct.
