Correct Answer: B

Rationale: The criticism that the information-processing approach ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence, suggests a limitation of the theory in not fully acknowledging that cognitive development continues throughout the lifespan. This criticism highlights a potential drawback of the approach in terms of its understanding of cognitive changes beyond adolescence. Choice A is incorrect because the criticism is not about underestimating the individual's contribution. Choice C is also incorrect as the criticism is not related to age-specific competencies. Choice D is incorrect as it focuses on a different aspect of the information-processing approach.

Correct Answer: B

Rationale: Newborn Mariana, who reacts strongly to unpleasant stimuli, is described as susceptible to colic. Colic is often characterized by excessive crying and fussiness in newborn babies, which can be challenging to console. This description suggests that Mariana's strong reactions to unpleasant stimuli may make her more prone to colic. Choices A, C, and D are incorrect because the strong reactions to unpleasant stimuli do not imply being easy to console, affect REM sleep, or responsiveness to swaddling.

Correct Answer: B

Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.

Correct Answer: B

Rationale: Ethnographies reveal that immigrant parents prioritize education as the surest way to improve life chances for their children. While learning English is important for integration, education is considered the key for better opportunities and success in the long term. Close ties to an ethnic community can provide support but may not directly lead to improved life chances. Moving into an urban area is not highlighted in the context of immigrant parents' views on improving life chances through their children's development.

Correct Answer: A

Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.
