What are some current economic indicators in referce to these questions?

Question

1) Cite an instance in which a surplus of a product led to decrease prices. What eventually happened?

(2) Cite an instance in which a shortage led to increased prices.

Answer 1

1) well i think that if you were running a shop and you got too many bannas for example before they went off you would need to sell them at a discounted price

2) like the petrol prices in the UK.  Barrels of oil are being sold for lower amounts of money now but the UK government has 60% of the £1.20 a litre so with the issues of global warming and also the strikes of oil tankers had led to increased prices due to the oil not being able to be transported across UK
