​For a given aggregate supply curve, an increase in aggregate demand will:

 a. ​increase real GDP.
 b. ​decrease real GDP.
 c. ​increase the real exchange rate.
 d. ​decrease the real interest rate.
 e. ​decrease the price level.

​Given an aggregate supply curve, a decrease in aggregate demand will:

 a. ​increase the real interest rate.
 b. ​increase real GDP.
 c. ​decrease real GDP.
 d. ​increase the price level.
 e. ​decrease the real exchange rate.

If aggregate demand increase then the aggregate demand (AD) curve shift to rightward. So, for a given aggregate supply curve if aggregate demand increase then the AD curve will shift to rightward. As a result, the real GDP will increase and the price will also increase. Hence except option a other options are not correct. Therefore, option a is the correct answer.

2) The answer is option c.

If aggregate demand decrease then the aggregate demand (AD) curve shift to leftward. So, for a given aggregate supply curve if aggregate demand decrease then the AD curve will shift to leftward. As a result, the real GDP will decrease and the price will also decrease. Hence except option c other options are not correct. Therefore, option c is the correct answer.
