Question

Assertion (A): Great circles are used to find the shortest distance between any two points on the earth's surface.

Reason (R): Great circle routes take into account weather or political restrictions.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

• Assertion (A) is true: Great circles represent the shortest distance between two points on the Earth's surface. These circles divide the Earth into two equal halves and provide the most direct path, used in air travel and navigation.
• Reason (R) is false: While great circle routes represent the shortest distance, they do not necessarily account for weather or political restrictions. Airlines or ships may choose routes that are more practical based on these factors, which could differ from the ideal great circle path.
