Answer to Question 1

C

Answer to Question 2

Holding all else equal means that everything other than the variable in question is assumed to remain constant. When we move along a demand curve we are assuming that all of the determinants of the demand for a good other than the price of the good (e.g., income, the prices of other goods) remain constant. When we move along a supply curve we are assuming that all of the determinants of the supply of a good other than the price of the good (e.g., wage rates, the price of raw material, technology) remain constant.
