Assertion (A): Two parallel straight-line demand curves have the same elasticity at the same price.

Reason (R): Parallel lines have the same slope.

Explanation

1. 01

   A is false: at the same price, the curve further out has a larger quantity, so P ÷ Q, and hence elasticity, is smaller.

2. 02

   R is true, but equal slopes do not give equal elasticities.
