The greatest changes in sensory, motor, and perceptual development happen in the first two years of life. When babies are first born, most of their senses operate in a similar way to those of adults. For example, babies are able to hear before they are born; studies show that babies turn toward the sound of their mothers' voices just minutes after being born, indicating they recognize the mother's voice from their time in the womb.
The exception to this rule is vision. A baby's vision changes significantly in its first year of life; initially it has a range of vision of only 8 - 12 inches and no depth perception. As a result, infants rely primarily on hearing; vision does not become the dominant sense until around the age of 12 months. Babies also prefer faces to other objects. This preference, along with their limited vision range, means that their sight is initially focused on their caregiver.
Which of the following best describes the mode of the passage?
Correct Answer: A
Rationale: The passage is expository as it provides factual information about the sensory, motor, and perceptual development in babies during the first two years of life. It explains how babies' senses develop, focusing on hearing and vision in their early stages. The passage presents these developmental milestones in a straightforward and informative manner, making it expository.
Choice B (narrative) is incorrect because the passage does not tell a story or present a sequence of events involving characters. Choice C (persuasive) is incorrect as there is no attempt to convince or persuade the reader of a particular viewpoint. Choice D (descriptive) is incorrect because the passage does not aim to create a vivid picture or impression using sensory details; instead, it focuses on providing clear information about sensory development in infants.
