Experience the Quality With Free HiSET Exam Questions That Helps Candidates Pass

“Slammed door” and “refused to talk” indicate anger. No evidence of happiness, fatigue, or confusion. Correct: A.

“Neither” is singular, so use “is.” Option B is grammatically correct. Options A and D use plural verbs incorrectly; C is incomplete. On HiSET grammar, subject-verb agreement with “neither” and “either” is tested often. Correct: B.

Higher input costs make production more expensive at every output level, so firms are willing to supply less at any given price. This is represented by a leftward shift of the supply curve. The result is a higher equilibrium price and lower equilibrium quantity, holding other factors constant. An increase in supply (A) would require lower input costs or productivity gains. Option C ignores a key determinant of supply: input prices. Option D confuses supply with demand; input costs affect producers, not consumers directly. On the HiSET, distinguishing movements along a curve (caused by price changes) from shifts of the curve (caused by determinants like input costs, technology, expectations, number of sellers) is a core skill. Therefore, B is correct.

A colon introduces a list after an independent clause. Only option C does this correctly. A places colon after verb, which is incorrect. Correct: C.

Option C uses proper commas in a list (Oxford comma optional but correct here). Options A, B, and D have errors. Correct: C.
