1. What is cystitis an inflammation of?
- A. Kidneys
- B. Bladder
- C. Ureters
- D. Urethra
Correct answer: B
Rationale: Cystitis is an inflammation of the bladder. It is typically caused by a bacterial infection and can lead to symptoms such as frequent urination, pain or burning during urination, and lower abdominal discomfort. The inflammation specifically affects the bladder lining. Choices A, C, and D are incorrect. Kidneys are not the site of inflammation in cystitis; they are associated with conditions like pyelonephritis. Ureters are tubes that connect the kidneys to the bladder, and the urethra is the tube that carries urine from the bladder to outside the body. Therefore, the correct answer is 'Bladder.'
2. Which of the following best describes the author's intent in the passage?
- A. to persuade
- B. to entertain
- C. to express feelings
- D. to inform
Correct answer: D
Rationale: The author's intent in the passage is to inform the reader about the historical events surrounding King James II, his family, and the succession of the English throne. The passage provides a detailed account of the lineage, religious affiliations, and the political implications of James II and his descendants. It does not aim to persuade, entertain, or express feelings, but rather presents a factual narrative of historical events. Therefore, choice D, 'to inform,' is the correct answer. Choices A, B, and C are incorrect because the passage is focused on presenting historical information rather than persuading, entertaining, or expressing emotions.
3. Which of the following is NOT a mechanism of evolution?
- A. Natural selection
- B. Genetic drift
- C. Lamarckism
- D. Mutation
Correct answer: C
Rationale: A) Natural selection is a mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to the next generation. B) Genetic drift is a mechanism of evolution that occurs due to random changes in allele frequencies in a population. C) Lamarckism, also known as the inheritance of acquired characteristics, is a discredited theory that suggests organisms can pass on traits acquired during their lifetime to their offspring. This mechanism has been largely rejected by the scientific community. D) Mutation is a mechanism of evolution that introduces new genetic variation into a population, which can lead to the emergence of new traits and adaptations over time.
4. The professor explained the concept clearly. What is the past participle of the verb 'explain'?
- A. explains
- B. explaining
- C. explained
- D. explanation
Correct answer: C
Rationale: The past participle of a verb is used to form various tenses and passive voice constructions. In this case, 'explained' is the correct past participle form of the verb 'explain'. The sentence structure indicates a completed action in the past, which aligns with the use of the past participle. Choice A, 'explains,' is the present tense form of the verb, not the past participle. Choice B, 'explaining,' is the present participle form of the verb, not the past participle. Choice D, 'explanation,' is a noun derived from the verb 'explain,' not the past participle form of the verb itself.
5. What is the main component that gives bones their rigidity and hardness?
- A. Collagen
- B. Calcium phosphate
- C. Cartilage
- D. Ligaments
Correct answer: B
Rationale: Calcium phosphate is the main component that gives bones their rigidity and hardness. It combines with calcium hydroxide to form hydroxyapatite crystals, which provide strength and structure to bones. Collagen, on the other hand, provides flexibility and tensile strength. Cartilage is a type of connective tissue found in joints, and ligaments are fibrous tissues that connect bones to other bones, but they do not contribute to the rigidity and hardness of bones.
