Let me know if correct for both

Suppose that low-productivity workers all have marginal products of 10 and high-
productivity workers all have marginal products of 12. The community has equal
numbers of each type of worker. A firm cannot directly tell the difference between
the two kinds of workers. Even after it has hired them, it won't be able to monitor
their work closely enough to determine which workers are of which type.
The local community college offers a course in microeconomics. High-productivity
workers think taking this course is as bad as a wage cut of $5, and low-productivity
workers think it is as bad as a wage cut of $9.
There is a separating equilibrium in which high-productivity workers take the
course and are paid $12 and low-productivity workers are paid $11.
There is a separating equilibrium in which high-productivity workers take the
course and are paid $17 and low-productivity workers do not take the course
and are paid $10.
There is a separating equilibrium in which high-productivity workers take the
course and are paid $12 and low-productivity workers do not take the course
and are paid $10.
There is no separating equilibrium, but there is a pooling equilibrium in which
everybody is paid $11.
There is no separating equilibrium and no pooling equilibrium.

In Rustbucket, Michigan, there are 200 used cars for sale, half of them are
good and half of them are lemons. Owners of lemons are willing to sell
them for $200. Owners of good used cars are willing to sell them for prices
above $1,100 but will keep them if the price is lower than $1,100. There is
a large number of potential buyers who are willing to pay $500 for a lemon
and $1,500 for a good car. Buyers can't tell good cars from bad, but original
owners know.
There will be an equilibrium in which all used cars sell for $1,000.
The only equilibrium is one in which all used cars on the market are
lemons and they sell for $500.
There will be an equilibrium in which lemons sell for $200 and good
used cars sell for $1,100.
There will be an equilibrium in which lemons sell for $500 and good
used cars sell for $1,500.
There will be an equilibrium in which all used cars sell for $650.
