A student wants to rewrite the following sentence: Entrepreneurs use their ideas to make money. He wants to use the word money as a verb, but he isn't sure which word ending to use. What is the appropriate suffix to add to money to complete the following sentence? Entrepreneurs __________ their ideas.

Correct Answer: A

Rationale: The correct answer is A: '-ize'. When '-ize' is added to 'money', it forms the word 'monetize'. 'Monetize' means to turn something into money or profit. Therefore, the sentence should read: 'Entrepreneurs monetize their ideas,' which accurately conveys the intended meaning of using ideas to generate profit. Choice B, '-ical', is incorrect as it does not create a verb from 'money'. Choices C and D, '-en' and '-ful', are also incorrect as they do not form a verb related to 'money' in the context of the sentence.

Correct Answer: D

Rationale: The teacher should advise the student that 'ain't' is a colloquial expression, and while it may be suitable in informal or conversational settings, it is not standard in academic writing. Using colloquialisms like 'ain't' in formal research papers can diminish the professionalism and clarity of the writing. Choice A is incorrect as the presence of a word in the dictionary does not solely determine its appropriateness in formal writing. Choice B is incorrect because the student's academic level does not justify the use of non-standard English. Choice C is incorrect as it focuses on the perceived uneducated sound of 'ain't' rather than its appropriateness in formal writing, which is the key concern for the research paper in question.

Correct Answer: A

Rationale: The sentence lacks parallel structure. The list of actions in the sentence should be presented in the same grammatical form. 'Travel to Italy,' 'take a Mediterranean cruise,' and 'go to Pompeii' should all be in the same form. To correct this, the sentence should be revised to: 'travel to Italy, take a Mediterranean cruise, visit Pompeii, and eat a lot of Italian food.' Choices B, C, and D are incorrect. The sentence is a complete sentence, not a fragment. There are no misplaced modifiers, and subject-verb agreement is not the issue in this sentence.

Correct Answer: A

Rationale: The prefix circum- means 'around' or 'surrounding.' In words like circumference (the distance around a circle), circumnavigate (to travel around something), and circumstance (the conditions surrounding an event), the prefix implies the idea of being around or encompassing. Choices B, C, and D are incorrect because the words do not primarily relate to travel, size, or area; instead, they share the common theme of being around or surrounding something.

Correct Answer: C

Rationale: This sentence is a complex sentence because it consists of an independent clause ('I accepted the change of seasons, and I started to appreciate the fall') and a dependent clause ('Although I wished it were summer'). The dependent clause cannot stand alone as a complete sentence and relies on the independent clause to make sense. Choice A (Compound) is incorrect because a compound sentence requires two independent clauses joined by a coordinating conjunction. Choice B (Simple) is incorrect as it does not account for the presence of both independent and dependent clauses. Choice D (Compound-Complex) is incorrect as it would require at least two independent clauses and one or more dependent clauses.
