Answer:
Please see below for answer
Step-by-step explanation:
1 Reduction in subsidy by government
The supply will be negatively affected as the production cost will get higher and it will get more difficult to meet the demand of the product.
2 Increase in price of wood
This will again have an impact on the supply as the production cost increases due to more expensive raw materials.
3 Need of cupboards increased in universities
The demand has increased in this case and the supply will have to be increased too if the demand is to be met.
4 Reduction in tax for both buyers and seller of cupboard
This will result in an increase in both supply and demand as more people might be able to afford the cupboards now as compared to before.
