Question

**Pointing out the benefits of the GST within a month of its implementation, Modi said that goods are being transported much faster, highways have become clutter-free and pollution levels had gone down and increased speed of trucks.**

Which of the following phrases (I), (II), and (III) given below should replace the phrase printed in bold letters to make the sentence grammatically correct? Choose the best option among the five given alternatives.

(I) are being lowered with the decreased  
(II) have come down with the increased  
(III) have been lowered because of decreasing

Accepted Answer

**Solution:**

1. The sentence is in the present tense, so the phrase replacing the bold part must align with this tense.

2. Option (II) "have come down with the increased" correctly fits the present perfect tense and logically connects pollution levels decreasing with increased speed of trucks.

3. Option (I) "are being lowered with the decreased" is incorrect because "decreased" is not properly linked and the phrase is awkward.

4. Option (III) "have been lowered because of decreasing" is also incorrect due to tense inconsistency and awkward phrasing.

5. Additionally, the speed of trucks is increasing, so pollution levels decreasing aligns with option (II).

6. The phrasal verb "come down" means to reduce or decrease, which suits the context here.

**Answer:** (b) Only (II) is correct
