Explanation:

Step1: Determine dose per administration

"Bid" means twice a day. So divide daily dose by 2: $\frac{1000\ \text{mg}}{2} = 500\ \text{mg per dose}$.

Step2: Calculate tablets per dose

Each tablet is 250 mg. Divide dose by tablet strength: $\frac{500\ \text{mg}}{250\ \text{mg per tablet}} = 2$ tablets.
