Correct Answer: C

Rationale: The word 'Although' is the correct choice as it is used to introduce a contrast between two ideas. In this sentence, it highlights the unexpected nature of Octavia being taller than her classmates despite being the youngest member of her class. This conjunction effectively conveys the discrepancy between her age and height in the context of the sentence. Choice A ('Despite') indicates a contradiction or contrast but does not capture the nuance of unexpectedness present in the sentence. Choice B ('Since') implies a causal relationship, which is not the intended meaning. Choice D ('Provided') suggests a condition or stipulation, which is not suitable for the context of the sentence. Therefore, 'Although' is the most appropriate choice.

Correct Answer: B

Rationale: The correct word should be 'coarse' instead of 'course' in this context. 'Coarse' means composed of relatively large parts or particles, which is the intended meaning in the sentence as it describes the type of flour used for the meatballs. On the other hand, 'course' means a route or direction taken, which does not fit the context here.

Correct Answer: D

Rationale: The word 'prefer' should be changed to 'prefers' to match the singular subject 'Louis.' The correct sentence should be: 'Fredericka always orders pancakes, but Louis prefers waffles.' Choice A 'always,' Choice B 'orders,' and Choice C 'but' are used correctly in the sentence and do not need any corrections.

Correct Answer: A

Rationale: The correct answer is A: 'Period'. The sentence 'Take this fast-acting cough medicine after your next meal.' is a complete sentence and requires a period at the end to indicate a full stop. A comma (Choice B) is not suitable here as it would create a comma splice. A colon (Choice C) is not needed as there is no introductory clause or list following it. A hyphen (Choice D) is used to join compound words or for other specific purposes, not to end a sentence.

Correct Answer: D

Rationale: The word 'ocurrence' is spelled incorrectly. The correct spelling is 'occurrence.' In this context, 'occurrence' refers to something happening or taking place, making it the appropriate term for the sentence. Choice A, 'Unfortunately,' is spelled correctly. Choice B, 'absences,' is spelled correctly. Choice C, 'regular,' is spelled correctly. Therefore, the incorrect spelling in the sentence is 'occurrence,' making it the right answer.
