GATE 2014 CS (CS1) – Question 6

General Aptitude · Verbal Aptitude: Grammar and Vocabulary · 2 marks · Multiple choice

The Palghat (Palakkad) Gap, about 30 km wide in the southern Western Ghats in India, is lower than the hilly terrain to its north and south. The exact reasons for its formation are unclear. It results in neighbouring Tamil Nadu regions receiving more South West monsoon rainfall and neighbouring Kerala regions having higher summer temperatures. What can be inferred?

  1. The gap is caused by high rainfall and high temperatures in southern Tamil Nadu and Kerala.
  2. Tamil Nadu and Kerala regions near the gap are low-lying.
  3. The gap’s low terrain significantly affects weather in neighbouring Tamil Nadu and Kerala.
  4. Higher summer temperatures cause higher rainfall near the gap.

Show answer and explanation

Correct answer: (C) The gap’s low terrain significantly affects weather in neighbouring Tamil Nadu and Kerala.

Explanation

The passage directly links the low gap with greater neighbouring Tamil Nadu rainfall and higher Kerala summer temperatures. Therefore **C**, a significant impact on regional weather, follows. It does not identify the cause of the gap or assert that all neighbouring regions are low-lying.
