1. Beriberi is a disease caused by a lack of ___________.

• A. thiamine
• B. vitamin C
• C. niacin
• D. protein

Correct answer: A

Rationale: Beriberi is a disease caused by a deficiency of thiamine, also known as vitamin B1. Thiamine is essential for the proper functioning of the nervous system and energy metabolism in the body. Without enough thiamine, individuals may develop symptoms such as weakness, fatigue, nerve damage, and heart problems, which are characteristic of beriberi. Vitamin C (choice B), niacin (choice C), and protein (choice D) deficiencies can cause other health issues but are not directly related to beriberi.

2. When a charged particle moves through a vacuum at a constant speed, it generates:

• A. An electric field only
• B. A magnetic field only
• C. Both an electric and magnetic field
• D. Neither an electric nor magnetic field

Correct answer: C

Rationale: A moving charged particle generates both an electric field and a magnetic field. The electric field is due to the charge itself, and the magnetic field is produced by the motion of the charge. Choice A is incorrect because a moving charged particle also generates a magnetic field. Choice B is incorrect because a moving charged particle generates both electric and magnetic fields. Choice D is incorrect as a moving charged particle generates fields due to its charge and motion.

3. What is a Contraindication?

• A. A reason to perform an action
• B. A reason something should not be done
• C. A warning of a possible side effect
• D. A reason something is advised

Correct answer: B

Rationale: A contraindication is a specific situation in which a drug, procedure, or treatment should not be used because it may be harmful. Choice A is incorrect because a contraindication advises against performing an action. Choice C is incorrect as it refers to a precaution regarding side effects rather than a reason not to proceed. Choice D is incorrect because a contraindication does not advise the use of something.

4. What type of chemical reaction involves the combination of two elements to form a product?

• A. Decomposition
• B. Combustion
• C. Synthesis
• D. Double replacement

Correct answer: C

Rationale: A synthesis reaction involves the combination of two or more substances to form a single, more complex product. In the context of chemical reactions, it specifically refers to the combination of two elements to form a compound. Therefore, the correct answer is C. Decomposition reactions involve the breakdown of a single compound into simpler substances (opposite of synthesis). Combustion reactions involve a substance reacting with oxygen to produce heat and light, not the combination of elements. Double replacement reactions involve the exchange of ions between two compounds, leading to the formation of two new compounds, not the combination of two elements.

5. Which word names an infected swelling with liquid inside?

• A. Blast
• B. Gash
• C. Hive
• D. Boil

Correct answer: D

Rationale: A boil is an infected swelling on the skin filled with pus, which is a type of liquid. It is typically caused by a bacterial infection in a hair follicle or oil gland. The other options, blast, gash, and hive, do not specifically describe an infected swelling with liquid inside like a boil does. A 'blast' is a sudden strong movement or gust, 'gash' refers to a long, deep cut or wound, and 'hive' is a skin reaction characterized by itchy welts.
