Answer:
Question 1 is Differences in perception versus reality
Question 2 is Rent ceilings reduce the quality and quantity of available housing.
Step-by-step explanation:
Question 1
Perception is a way of regarding, understanding, or interpreting something; a mental impression as result of pre-existing notions. Shen judgement was based on her knowledge of economics of free markets without taking into consideration of exceptions.
Reality on the other hand is the state of things as they actually exist, as opposed to an idealistic or notional idea of them. Shen with her economics knowledge understands that the situation on ground does not conform with what Valerie knows. This is because perception is inherently flexible and speculative while reality disrespects viewpoints and view angles and is inherently rigid and factual.
Question 2
Rent ceilings stimulate demand and this cause shortages. Where the ceiling is set, there is more demand than at the equilibrium price.
This leads to shortage of supply of rent housing. This is because investors and landlords will stop building new houses or apartments to satisfy existing or increasing quantity demand. This shortage of supply somehow will lead to search activity and invariably affect the quality and quantity of available housing.
