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: C

Rationale: Babies primarily rely on the sense of touch during their early development. Their sense of touch is one of the first senses to develop, allowing them to explore and understand the world around them. Touch helps babies bond with caregivers, provides comfort, and facilitates learning about different textures and sensations. While vision, hearing, and smell are also important, touch plays a crucial role in infants' early development and communication. The provided extract explains that babies initially rely on hearing and later on vision, with touch being essential for early bonding and exploration, making it the primary sense in infancy.

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: 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.

Correct Answer: C

Rationale: The statement 'It was irresponsible for Julia to leave work early' is an opinion because it reflects a judgment or evaluation of Julia's actions, rather than stating a fact. The other statements (A, B, D) provide factual information about events that occurred in the passage. Option A states a fact about Julia being asked by her boss; option B explains the reason for Julia being late; option D provides a reason for Julia feeling tired. These are not opinions but rather statements of events or circumstances.
