1. When __________, newborn Takeo's toes should fan out and curl as his foot twists in.

Correct answer: D

Rationale: The correct answer is D because the description of the twisting and fanning out of newborn Takeo's toes suggests the Babinski reflex, which is typically elicited by stroking the sole of the foot from toe to heel. The Babinski reflex is a normal response in newborns and indicates proper neurological development. Choices A, B, and C are incorrect as they do not elicit the specific response described in the question.

2. Students who are foreign-born or first-generation Americans _______ than students of native-born parents.

Correct answer: C

Rationale: According to the information provided in the text box 'CULTURAL INFLUENCES: Immigrant Youths: Adapting to a New Land' on page 32, students who are foreign-born or first-generation Americans often achieve in school as well as or better than students of native-born parents. This implies that they excel academically despite facing challenges related to cultural adaptation and assimilation. Choices A, B, and D are incorrect because the provided information specifically highlights the academic achievement of foreign-born or first-generation American students compared to students of native-born parents, not their likelihood of committing delinquent acts, obesity rates, or self-esteem levels.

3. A __________ is a means of building schemes in which an infant who has stumbled onto a new experience caused by his or her own motor activity tries to repeat the event again and again.

Correct answer: B

Rationale: A circular reaction is a process where an infant repeats a specific action to explore and learn about the environment through their own motor activity. This repetition helps the infant to understand the consequences of their actions and build cognitive schemes. Sensorimotor reflex (choice A) refers to automatic responses to stimuli, not a purposeful repetition of actions to learn. Mental representation (choice C) involves internal cognitive structures to represent objects or events in the mind, which is different from the repetitive behavior described in the question. Goal-directed behavior (choice D) is purposeful and intentional, unlike the repetitive nature of circular reactions in infants' learning process.

4. It is difficult to isolate the precise damage caused by illegal drugs during pregnancy because __________.

Correct answer: D

Rationale: The difficulty in isolating the precise damage caused by illegal drugs during pregnancy is due to the fact that drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses. This makes it challenging to identify the specific impact of each individual factor on prenatal development. Choices A, B, and C are incorrect because they do not address the complexity of the situation involving drug users during pregnancy. Most drug-using mothers refusing to participate in teratology research, the majority of babies not surviving, or drug-using mothers quitting during the first trimester do not directly explain the difficulty in isolating the precise damage caused by illegal drugs during pregnancy.

5. Which statement about a blastocyst is true?

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.
