An unusually warm winter will

The correct answer is: C. Shift the demand curve for gloves leftward.

An unusually warm winter will decrease the demand for gloves. This is because people will be less likely to wear gloves when it is warm outside. As a result, the demand curve for gloves will shift leftward.

The supply curve of gloves is not affected by the weather. This is because the supply of gloves is determined by the cost of producing gloves, not by the weather. Therefore, the supply curve of gloves will not shift.

Here is a more detailed explanation of each option:

• Option A: Shift the supply curve of gloves leftward. This is incorrect because the supply curve of gloves is not affected by the weather. The supply curve of gloves is determined by the cost of producing gloves, not by the weather. Therefore, the supply curve of gloves will not shift.
• Option B: Shift the demand curve for gloves rightward. This is incorrect because the demand for gloves will decrease, not increase, in an unusually warm winter. This is because people will be less likely to wear gloves when it is warm outside. As a result, the demand curve for gloves will shift leftward.
• Option C: Shift the demand curve for gloves leftward. This is the correct answer because the demand for gloves will decrease in an unusually warm winter. This is because people will be less likely to wear gloves when it is warm outside. As a result, the demand curve for gloves will shift leftward.
• Option D: Shift the supply curve of gloves rightward. This is incorrect because the supply curve of gloves is not affected by the weather. The supply curve of gloves is determined by the cost of producing gloves, not by the weather. Therefore, the supply curve of gloves will not shift.
