Correct Answer: A

Rationale: A letter written by a local farmer who witnessed the Battle of Gettysburg would be a primary source as it provides direct firsthand accounts and observations from someone who was present during the event. This source would offer valuable insights and perspectives for an article on the Battle of Gettysburg. Choice B, a documentary produced by a local TV station, is a secondary source as it interprets and presents information about the battle rather than providing direct firsthand accounts. Choice C, a novelization of the battle written by the great-grandson of a Union soldier, is also a secondary source as it involves interpretation and creative storytelling rather than direct eyewitness information. Choice D, a history textbook for a college-level course in American history, is a tertiary source that compiles information from various primary and secondary sources rather than presenting original firsthand accounts.

Correct Answer: B

Rationale: The correct sequence of the author's actions based on the extract is as follows: the author looked at the house on Forest Road first, then two houses that were too small, followed by a house with a yard that was too small, and finally a house that was too expensive. Therefore, choice B correctly lists the author's actions in the given sequence. Choice A is incorrect as it reverses the order of the second and third houses visited. Choice C is incorrect as it includes a house with only one bathroom, which was not mentioned in the extract. Choice D is incorrect as it places the house on Forest Road last, whereas it was actually the first house visited.

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: 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: B
