Answer to Question 1

A

Answer to Question 2

The spacing of the isobars indicates the amount of pressure change occurring over a given distance. A steep pressure gradient, with closely spaced isobars, means faster wind speeds. A weak pressure gradient, with far-spaced isobars, means slower wind speeds.
