1. Which word is used incorrectly in the following sentence? Her mentor’s advice was bound to affect her final decision.

• A. mentor’s
• B. advice
• C. effect
• D. decision

Correct answer: C

Rationale: In the given sentence, the word 'effect' is used incorrectly. In this context, the word 'affect' should be used instead of 'effect.' 'Affect' is a verb that means to influence or have an impact on something, while 'effect' is a noun that represents the result or outcome of an action. Therefore, to convey the intended meaning that her mentor's advice was bound to influence or impact her final decision, the correct word should be 'affect,' not 'effect.' The other options ('mentor’s,' 'advice,' 'decision') are used appropriately in the sentence and do not contain any errors.

2. What charge do Group IIA elements typically have?

• A. 1
• B. +2
• C. -3
• D. 0

Correct answer: B

Rationale: Group IIA elements belong to the alkaline earth metals group in the periodic table. These elements typically have a charge of +2 because they readily lose two electrons to achieve a stable electron configuration. Therefore, the correct answer is B - +2. Choice A (1) is incorrect because Group IIA elements lose two electrons, not one. Choice C (-3) is incorrect because Group IIA elements do not gain electrons to have a negative charge. Choice D (0) is incorrect because Group IIA elements do lose electrons and have a positive charge, not a neutral charge.

3. What form of radiation is composed of electrons traveling at around 16,000 km/sec?

• A. Alpha radiation
• B. Beta radiation
• C. Gamma radiation
• D. Delta radiation

Correct answer: B

Rationale: Beta radiation is composed of high-energy electrons (β- particles) or positrons (β+ particles) traveling at considerable speeds. In this case, the electrons traveling at around 16,000 km/sec align with the characteristics of beta radiation, making it the correct choice. Alpha radiation consists of helium nuclei, gamma radiation is electromagnetic radiation of high frequency, and delta radiation is not a recognized form of radiation, making them all incorrect choices.

4. Contact dermatitis occurs through the sense of ___________.

• A. smell
• B. taste
• C. touch
• D. sight

Correct answer: C

Rationale: Contact dermatitis occurs through the sense of touch when the skin comes into direct contact with irritants or allergens, leading to an inflammatory reaction. This condition is commonly caused by the skin being in contact with items like certain chemicals, fabrics, plants, or metals, resulting in redness, itching, and sometimes blisters. The other choices (smell, taste, sight) do not relate to the cause of contact dermatitis, which specifically involves the skin's direct contact with irritants or allergens.

5. What is the primary function of the large intestine?

• A. To absorb water and form solid waste
• B. To produce digestive enzymes
• C. To secrete hormones
• D. To transport nutrients

Correct answer: A

Rationale: The correct answer is A. The primary function of the large intestine is to absorb water from the remaining indigestible food matter and form solid waste (feces) for excretion. This process helps in reabsorbing water and electrolytes, resulting in the formation of feces by compacting the waste material. Choices B, C, and D are incorrect because the large intestine is not responsible for producing digestive enzymes, secreting hormones, or transporting nutrients. These functions are typically associated with other parts of the digestive system.
