Correct Answer: B

Rationale: The correct word to substitute for the underlined words 'the children' in the sentence would be 'their' to ensure clarity and proper possessive form. Using 'their' makes it clear that the photographs belong to the children. Choice A 'its' is incorrect as it refers to singular possession. Choice C 'they' is a pronoun and does not indicate possession. Choice D 'his' is incorrect as it is singular and refers to a male possessive form, which does not match the plural 'children' in the sentence.

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: In this sentence, 'to throw' is the correct form to use after the verb 'started' to indicate the action that the children began doing. The infinitive form 'to throw' is needed after the verb 'started' to show the purpose or action that is about to happen. When an action follows another action that has already started, the infinitive form is typically used to express the purpose or intention behind the subsequent action, making 'to throw' the most appropriate choice. Choices A, C, and D are incorrect because 'throw' is not the correct form to follow 'started' as it needs an infinitive form, 'threw' is the past tense which is not suitable in this context, and 'threwing' is an incorrect form of the verb that does not exist in standard English.

Correct Answer: C

Rationale: The word 'draw' is used incorrectly in the sentence. The correct word that needs to be used is 'criteria' instead of 'criterion' to maintain subject-verb agreement. The correct sentence should be: 'Which criteria were used to draw a conclusion about their findings?' 'Draw' should be 'were drawn' to match the plural subject 'criteria.' The other choices are correct in the sentence and do not contain any errors.

Correct Answer: C

Rationale: In the sentence, the phrase 'the farmhouse' is misplaced because it should come before 'behind' to clarify the location properly. The corrected sentence should read, 'There was a long fence behind the farmhouse made of crisscrossed logs.' Placing 'the farmhouse' after 'behind' creates a clearer and more logical sentence structure. Choice A, 'There,' is correct in its placement at the beginning of the sentence. Choice B, 'a long fence,' is also correctly positioned as it describes the object being referred to. Choice D, 'made of crisscrossed logs,' is properly placed to provide additional detail about the fence.
