What is the most effective way to combine the two sentences below?

Correct Answer: D

Rationale: The correct answer is D. This choice effectively combines the two sentences with the use of a comma before 'and' to connect the two related but independent clauses. The comma helps to separate the contrasting information about German cuisine and the Sunday dinner, maintaining a clear and coherent structure. Choices A, B, and C are incorrect because they either lack the necessary punctuation or use 'but' instead of 'and,' which disrupts the flow of the combined sentence and fails to convey the intended relationship between the two ideas.

Correct Answer: C

Rationale: When addressing a formal letter to the school board, 'Dear Sir and/or Ma'am' is the most appropriate greeting as it shows respect and professionalism. Choice A, 'Dearest School Board,' is too informal and overly personal for a professional communication. Choice B, 'To Whom It May Concern,' is more suitable for general inquiries when the recipient is unknown, not for addressing a specific group like a school board. Choice D, 'Hello all,' is too casual and lacks the formality required when addressing a school board.

Correct Answer: B

Rationale: The correct answer is B because 'aural' and 'oral' are homophones, but they have different meanings. 'Aural' refers to hearing, while 'oral' refers to the mouth or spoken words. In the context of treating mouth ulcers, the correct term should be 'oral paste.' Choices A, C, and D do not contain homophone errors. In choice A, 'heard' is correctly used in the context of listening. Choice C is grammatically correct and does not involve homophones. Choice D correctly uses 'effect' and does not involve homophones.

Correct Answer: C

Rationale: The correct chronological order for the sentences within a paragraph should follow the sequence of events logically. In this case, 'I, II, III, IV' is the correct order. Sentence I usually sets the stage or introduces the main idea, followed by sentence II, which provides additional information. Sentence III usually presents the climax or a turning point, leading to sentence IV, which wraps up the paragraph. Choice C, 'I, II, III, IV,' maintains this logical progression, making it the best chronological order. Choices A, B, and D do not follow a coherent chronological sequence and disrupt the flow of events within the paragraph.

Correct Answer: B

Rationale: The correct answer is B. This sentence effectively follows the conventions of standard written English by clearly presenting the subject ('The two brothers, Wilbur and Orville Wright') and the verb ('tested') with appropriate punctuation. Choice A introduces an unnecessary comma and could be more concise. Choice C changes the tense of the verb to 'were testing,' which is not required for the context provided. Choice D creates a more awkward sentence structure by placing the location at the beginning and using 'came and tested,' which is less direct than 'tested'. Thus, Choice B is the most effective and grammatically correct option.
