A. Deficiency
B. Surplus

A. Deports
B. Exports
C. Reports
D. Imports

Correct answer: D

Rationale: The US imports most of its silicone chips from Japan and China, indicating that the silicone chips are being brought into the US from these countries. 'Imports' refers to the act of bringing goods or services into one country from another, which accurately describes the scenario described in the question. The other choices are incorrect: 'Deports' means expelling individuals from a country, 'Exports' mean sending goods to another country, and 'Reports' mean providing information or data.

3. What is the meaning of Regulations?

A. Rules for Conduct
B. Official Standards
C. Personal Guidelines
D. Suggestions

Correct answer: A

Rationale: Regulations refer to rules or directives established by authorities to govern conduct or actions. Therefore, the correct answer is A - 'Rules for Conduct.' Choice B, 'Official Standards,' is incorrect as regulations go beyond just setting standards to include specific rules for behavior. Choice C, 'Personal Guidelines,' is incorrect as regulations are not individualized but are generally applicable rules. Choice D, 'Suggestions,' is incorrect as regulations are mandatory and carry legal weight, unlike suggestions which are optional and not binding.

4. Which sentence contains a subject-verb agreement error?

A. The group of students is very smart
B. The team of players is winning
C. The list of items is on the table
D. The pile of books is heavy

Correct answer: B

Rationale: The correct answer is 'B: The team of players is winning.' The error in this sentence is a subject-verb agreement issue. 'Team' is a singular noun, so it should take a singular verb 'is' instead of 'are.' The subject-verb agreement rule states that singular subjects should be paired with singular verbs, while plural subjects should be paired with plural verbs. Choices A, C, and D all demonstrate correct subject-verb agreement as they correctly match singular subjects ('group,' 'list,' 'pile') with singular verbs ('is,' 'is,' 'is').

5. A condition that is chronic is ___________.

A. harmless
B. critical
C. contagious
D. recurring

Correct answer: D

Rationale: The correct answer is D, 'recurring.' A chronic condition is one that is ongoing or long-lasting, implying that it persists or recurs over a prolonged period of time. Choices A, B, and C are incorrect because chronicity does not necessarily imply harmlessness, criticality, or contagion; rather, it refers to the persistent or recurring nature of the condition.
