1. Which word correctly completes the sentence: 'He was _____ by the kindness of strangers.'

• A. affected
• B. infected
• C. effected
• D. defected

Correct answer: C

Rationale: The correct answer is 'effected.' In this context, 'effected' means to produce a result or impression, which aligns with the emotional impact of the strangers' kindness. The other choices are incorrect: A) 'affected' might seem plausible, but 'effected' is a better fit as it implies a direct result. B) 'infected' is incorrect as it implies a negative or harmful impact, which is not the intended meaning. D) 'defected' means to abandon allegiance, which is not relevant in the given sentence.

2. Which of the following labels best describes the previous passage?

• A. comparison essay
• B. definition essay
• C. cause and effect essay
• D. persuasive essay

Correct answer: C

Rationale: The passage delves into the relationship between magnesium intake and health outcomes, highlighting how deficiencies in magnesium can lead to various health issues. It discusses how different factors, such as gastrointestinal disorders or dietary habits, can cause magnesium depletion and its subsequent effects on the body. This focus on exploring the cause-and-effect connections between magnesium levels and health conditions aligns with the characteristics of a cause and effect essay, making choice C the most appropriate. Choices A, B, and D are incorrect because the passage does not focus on comparing different concepts, providing definitions, or persuading the reader of a particular viewpoint.

3. Which part of the brain is responsible for balance and coordination?

• A. Cerebrum
• B. Cerebellum
• C. Medulla oblongata
• D. Thalamus

Correct answer: B

Rationale: The correct answer is the cerebellum. The cerebellum is responsible for balance, coordination, and fine motor control. It integrates sensory information from the vestibular system in the inner ear and proprioceptive information from muscles and joints to coordinate voluntary movements. The cerebrum is primarily involved in higher brain functions like thinking and decision-making. The medulla oblongata controls vital autonomic functions such as breathing and heart rate. The thalamus serves as a relay station for sensory information before sending it to the cerebral cortex for further processing.

4. The tonsils and adenoids, located in the throat, are part of the:

• A. Lymphatic system
• B. Endocrine system
• C. Respiratory system
• D. Digestive system

Correct answer: A

Rationale: The tonsils and adenoids are part of the lymphatic system, not the respiratory, endocrine, or digestive systems. The lymphatic system plays a crucial role in the body's defense against infections and diseases by producing white blood cells and lymphatic fluid, which help in filtering harmful substances. The respiratory system is primarily responsible for breathing and gas exchange in the body, the endocrine system regulates hormones, and the digestive system is involved in the breakdown and absorption of nutrients from food. Therefore, the correct answer is the lymphatic system.

5. Simplify the following expression: 5/9 × 15/36

• A. 5/36
• B. 8/27
• C. 10/17
• D. 15/27

Correct answer: A

Rationale: To simplify the given expression, multiply the numerators together and the denominators together. 5/9 × 15/36 = (5 × 15) / (9 × 36) = 75 / 324. Now, simplify the resulting fraction by finding the greatest common divisor (GCD) of 75 and 324, which is 3. Divide both the numerator and denominator by 3 to get the simplified fraction: 75 ÷ 3 / 324 ÷ 3 = 25 / 108. Therefore, the simplified form of 5/9 × 15/36 is 25/108, which is equivalent to 5/36. Choice A, 5/36, is the correct answer. Choice B, 8/27, is incorrect as it does not match the simplified form of the expression. Choice C, 10/17, is unrelated and does not result from the given multiplication. Choice D, 15/27, does not correspond to the simplification of the given expression.
