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: 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: B

Rationale: The correct answer is B: Water immediately. After planting potatoes, the first step should always be to water them immediately. This is crucial to settle the soil around the newly planted potatoes, ensuring good contact between the roots and the soil. Watering helps kickstart the growth process and provides the necessary moisture for the newly planted potatoes to establish themselves successfully. Choices A, C, and D are incorrect because mounding soil, mixing fertilizer/compost, and spacing potatoes should be done before or during planting, not immediately after.

Correct Answer: A

Rationale: By observing the headings provided in the extract, we can see that they are sorted alphabetically starting from 'Gray Tree Frog.' Following this alphabetical order, the next heading to be inserted in the blank spot would also come alphabetically next, which is 'Gray Tree Frog.' Choices B, C, and D do not follow the alphabetical pattern established by the existing headings and are therefore incorrect.

Correct Answer: B

Rationale: The correct answer is B. The passage explains that the kingsnake mimics the venomous coral snake's markings to deter predators, particularly hawks and eagles, which cannot differentiate between the two species. This implies that both the coral snake and the kingsnake face similar threats from predators in their shared habitat. Choice A is incorrect because the passage clearly states that the kingsnake is nonvenomous, so it is not dangerous to humans. Choice C is incorrect as the passage highlights that not all snakes with flashy markings are venomous, emphasizing the need for caution. Choice D is incorrect as there is no mention of the kingsnake changing its markings in response to the presence of hawks or eagles in the passage.
