Correct Answer: D

Rationale: Based on the passage provided, there is no indication that Julia will find a job closer to her home, lose her job, or feel guilty and return to work. The passage simply states that Julia is tired and ready to go home, indicating that she will likely drive home and go to sleep. Throughout the passage, Julia faces a series of frustrating events that culminate in her decision to leave work and head home. There is no mention of job hunting, job loss, or feelings of guilt, making these options unsupported by the text.

Correct Answer: A

Rationale: Choice A weakens the author's argument by highlighting a potential conflict of interest. If the cited study was funded by a company offering discounted tutoring, it could introduce bias and question the credibility of the study's findings. This revelation could cast doubt on the objectivity and reliability of the research, ultimately undermining the argument based on the cited study. Choices B, C, and D do not directly impact the credibility or objectivity of the cited study, so they would not significantly weaken the author's argument.

Correct Answer: D

Rationale: In the context provided, the word 'testament' most likely refers to evidence. A testament can be something that serves as proof or confirmation of a fact or situation. In this case, it is used in a non-religious sense to indicate evidence or proof. The other choices are incorrect as 'story' does not fit the context, 'surprise' is not related to the owners' skills mentioned, and 'artifact' does not align with the discussion of the restaurant's success.

Correct Answer: D

Rationale: The author's conclusion about the house on Pine Street is that it was too expensive. This can be inferred from the description provided in the text, where it is mentioned that although the house had enough space inside, it didn't have a big enough yard for their dogs, and the cost of the house was well above their price range. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not align with the evidence from the text, which clearly points to the cost being the main issue with the house on Pine Street.

Correct Answer: D

Rationale: Option D is the most concise summary of the passage as it encapsulates the main idea that the passage focuses on the changes in babies' senses during their first year of life. The passage explains how babies are born with sensory abilities similar to adults but highlights the significant changes that occur during the first year, particularly in vision development. While the other options touch on specific aspects mentioned in the passage, they do not capture the overall essence of the passage, which emphasizes the dynamic and transformative nature of babies' sensory experiences in their first year.
