College Algebra
Question 1
If f(x) = 2x² − 3x + 1, what is f(−2)?
f(−2) = 2(4) − 3(−2) + 1 = 8 + 6 + 1 = 15. A common trap is B, which forgets to negate the middle term.
Introductory Psychology
Question 2
Which neurotransmitter is most associated with the brain's reward pathway and is implicated in addiction?
Dopamine in the mesolimbic pathway drives reward learning and is the primary neurotransmitter hijacked by addictive drugs. Serotonin is closer to mood regulation.
American Government
Question 3
Which of the following powers is RESERVED to the states under the Tenth Amendment?
Marriage licensing is a classic reserved power — not delegated to the federal government and not prohibited to the states. A, B, D, E are all enumerated federal powers.
Biology
Question 4
In eukaryotic cells, ATP is produced primarily in which organelle?
Oxidative phosphorylation occurs on the inner mitochondrial membrane, producing the bulk of cellular ATP. Ribosomes synthesize proteins, not ATP.
Macroeconomics
Question 5
If the Federal Reserve sells government bonds on the open market, what is the most likely immediate effect?
Selling bonds withdraws reserves from commercial banks, contracting the money supply. This is contractionary open-market policy — the opposite of A and B.
