1. What is the cycle of infection?

• A. Reservoir host, means of exit, means of transmission, means of entrance, susceptible host
• B. Entry point, transmission, replication, exit, susceptible host
• C. Susceptible host, replication, transmission, entry, exit
• D. Transmission, replication, entry, exit, susceptible host

Correct answer: A

Rationale: The correct answer is A: 'Reservoir host, means of exit, means of transmission, means of entrance, susceptible host.' This cycle of infection involves the pathogen starting in a reservoir host, exiting through a means, being transmitted to another host, entering the new host through a means, and ultimately infecting the susceptible host. Choices B, C, and D are incorrect because they do not follow the correct sequence of events in the cycle of infection.

2. What type of error occurs in the sentence 'Everyone knew who the culprit was, except for me'?

• A. Subject-verb agreement
• B. Misplaced modifier
• C. Dangling participle
• D. Pronoun-antecedent agreement

Correct answer: B

Rationale: The error in the sentence is a misplaced modifier. The phrase 'except for me' should ideally modify 'me,' but it is incorrectly placed after 'knew,' leading to confusion about who the exception applies to. 'Subject-verb agreement' is incorrect as there is no disagreement between the subject and the verb. 'Dangling participle' is incorrect as there are no dangling participles in the sentence. 'Pronoun-antecedent agreement' is incorrect as the pronoun 'me' correctly refers to the antecedent 'I'; the issue lies with the placement of the modifier.

3. Which of the following is a run-on sentence?

• A. I went to the store, and I bought some milk.
• B. The cat slept on the mat; she purred softly.
• C. He studied hard, so he passed the exam.
• D. We can go to the park, or we can stay home.

Correct answer: B

Rationale: The correct answer is B: 'The cat slept on the mat; she purred softly.' This sentence is a run-on because it contains two independent clauses ('The cat slept on the mat' and 'she purred softly') without proper punctuation. Choice A is incorrect as it is a compound sentence with a coordinating conjunction 'and' joining two independent clauses. Choice C is also incorrect as it is a compound sentence connected by a coordinating conjunction 'so.' Choice D is not a run-on sentence; it is a compound sentence with a coordinating conjunction 'or' joining two independent clauses.

4. The teacher shared several apothegms with the class, hoping that the short, wise sayings would inspire thoughtful discussions.

• A. instructions
• B. questions
• C. sayings
• D. lectures

Correct answer: C

Rationale: In this context, apothegms refers to short, wise sayings meant to convey wisdom or provoke thought. Apothegms are concise and insightful, serving as nuggets of wisdom. The term 'instructions' implies a set of directions or guidelines, not reflective of the nature of apothegms. 'Questions' are queries seeking information or answers, not synonymous with wise sayings. 'Lectures' are formal presentations or speeches, which are more extensive and detailed compared to the concise nature of apothegms.

5. Which of the following structures is responsible for preventing the backflow of blood from the left ventricle into the left atrium?

• A. Aortic valve
• B. Pulmonary valve
• C. Tricuspid valve
• D. Mitral valve

Correct answer: D

Rationale: The correct answer is D, the Mitral valve. The mitral valve, also known as the bicuspid valve, is situated between the left atrium and the left ventricle. Its primary function is to prevent the backflow of blood from the left ventricle into the left atrium during ventricular contraction. The other choices are incorrect because: A) The aortic valve prevents backflow from the aorta into the left ventricle. B) The pulmonary valve prevents backflow from the pulmonary artery into the right ventricle. C) The tricuspid valve prevents backflow from the right ventricle into the right atrium.
