Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).

Assertion (A): Jet streams discovered during World War II are high altitude easterly winds.
Reason (R): Jet streams flow with a speed of 300-500 km/hour.

Answer & Solution

Answer: (Detailed Solution Below)

Option B: (A) is false, but (R) is true

Detailed Solution:

The correct answer is “(A) is false, but (R) is true”.
Jet streams are not high-altitude easterly winds. Instead, they are westerly winds, meaning they flow from west to east. They were indeed discovered during World War II when pilots noticed strong winds affecting their flights.

Jet streams flow at speeds ranging from 300 to 500 km/h, and in some cases, they can reach even higher speeds.
