1. Which of the following statements regarding the working of the heart is not correct?

• A. The atria contract, and the valves open to allow blood into the ventricles.
• B. The heartbeat begins when the heart muscles relax, and blood flows into the atria.
• C. The valves close to stop blood from flowing backward.
• D. The ventricles contract, forcing blood to leave the heart.

Correct answer: B

Rationale: The correct answer is B because the heartbeat actually begins when the heart muscles relax, allowing the chambers to fill with blood. The contraction phase follows, which propels blood out of the heart. The other statements are accurate in describing the normal sequence of events in the heart's functioning: the atria contract to push blood into the ventricles, the valves close to prevent backflow of blood, and the ventricles contract to pump blood out of the heart.

2. Which event is out of sequence in the story?

• A. Installing the dog run in the backyard.
• B. Enrolling the dog in obedience classes.
• C. The physical exam confirming the dog's health.
• D. The dog's next obedience class.

Correct answer: D

Rationale: The correct answer is D because the story describes the sequence of events after adopting the dog. After bringing Robin home, the sequence includes confirming her health with a physical exam, buying supplies, installing a dog run, and then taking her to the vet. Enrolling her in obedience classes is mentioned to start the following week, making it the next logical step. Therefore, the detail about the dog's next obedience class is not out of sequence. Choices A, B, and C are all in the correct sequence according to the events described in the story.

3. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

• A. Hypertrophy
• B. Atrophy
• C. Fibrosis
• D. Rigor mortis

Correct answer: B

Rationale: Atrophy is the correct term for the process by which muscle tissue wastes away due to disuse or lack of nutrients. It is essential to differentiate atrophy from hypertrophy, which is the increase in muscle size due to exercise or strength training. Fibrosis involves the formation of excess fibrous connective tissue, which is distinct from muscle wasting. Rigor mortis, on the other hand, is the stiffening of muscles that occurs after death and is not related to muscle wasting during life.

4. Which of the following statements represents an EXAGGERATED claim in support of the argument presented in the passage?

• A. In the United States, the foreign language requirement for high school graduation is decided at the state level.
• B. Studying a foreign language has become increasingly important for the global economy.
• C. High school graduates with foreign language credits have been shown to have an increased college acceptance rate.
• D. Students who did not study a foreign language often find themselves unable to obtain a job at all.

Correct answer: D

Rationale: While it is true that studying a foreign language can enhance one's job prospects and competitiveness in the job market, claiming that students who did not study a foreign language often find themselves unable to obtain a job at all is an exaggerated statement. Many factors contribute to employability, and while language skills can be advantageous, they are not the sole determining factor in securing employment.

5. Which of the following is used to record the measurable electrical activity of the brain?

• A. CAT scan
• B. MRI scan
• C. Electroencephalogram (EEG)
• D. X-ray

Correct answer: C

Rationale: The correct answer is an Electroencephalogram (EEG). An EEG is specifically designed to record the measurable electrical activity of the brain. It does so by using small, flat metal discs (electrodes) attached to the scalp to detect brain activity. This test is crucial in diagnosing various conditions like seizures, epilepsy, head injuries, dizziness, headaches, and brain tumors. The other options, CAT scan, MRI scan, and X-ray, are imaging techniques that do not directly measure the brain's electrical activity. CAT scan and MRI scan provide detailed images of the brain's structure, while X-ray is more suited for visualizing bone structures or dense tissues.
