1. Solve |x| = 10.

• A. -10, 10
• B. -11, 11
• C. -12, 12
• D. -13, 13

Correct answer: A

Rationale: The absolute value of x is equal to 10 when x is either -10 or 10. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not satisfy the equation |x| = 10. For choice B, -11 and 11 do not satisfy the condition. Choices C and D also do not provide solutions that meet the equation's requirement.

2. Which valve prevents backflow into the atrium when the ventricles contract?

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

Correct answer: B

Rationale: The tricuspid valve (right atrioventricular valve) prevents backflow into the right atrium when the right ventricle contracts. This valve ensures that blood flows in the correct direction, preventing regurgitation into the atrium. The pulmonary valve is responsible for preventing backflow into the right ventricle from the pulmonary artery. The mitral valve prevents backflow into the left atrium, and the aortic valve prevents backflow into the left ventricle from the aorta. Therefore, the correct answer is the tricuspid valve as it specifically addresses the scenario of backflow into the atrium during ventricular contraction.

3. Which of the following correctly orders the route of a fetus during childbirth?

• A. Uterus, cervix, vagina
• B. Cervix, uterus, vagina
• C. Uterus, vas deferens, vagina
• D. Ovary, fallopian tube, uterus

Correct answer: A

Rationale: The correct route of a fetus during childbirth is from the uterus, through the cervix, and then out through the vagina. The contractions of the uterus help push the fetus through the cervix and out through the vaginal canal during childbirth. Choice B is incorrect as it reverses the order of the cervix and uterus. Choice C is incorrect as it includes the vas deferens, which is not part of the female reproductive system. Choice D is incorrect as it lists structures from the female reproductive system but in the wrong order for childbirth.

4. Which of the following is NOT a common location for lymph nodes?

• A. Groin
• B. Armpit
• C. Neck
• D. Liver

Correct answer: D

Rationale: The correct answer is 'D: Liver.' The liver is not a common location for lymph nodes. Lymph nodes are small, bean-shaped structures distributed throughout the body, including common sites like the groin, armpit, and neck. They play a crucial role in the immune system by filtering lymph fluid and trapping harmful substances, aiding the body in defending against infections and diseases. The liver, on the other hand, is an organ responsible for various functions like detoxification, metabolism, and storage, but it does not house lymph nodes.

5. Which sentence avoids a dangling modifier?

• A. Walking down the street, a bird swooped down from a tree.
• B. Having finished the report, it was time for lunch.
• C. Reading the book, I learned a lot about ancient history.
• D. Exhausted from the hike, the tent was a welcome sight.

Correct answer: C

Rationale: Option C correctly places the participle phrase 'Reading the book' directly in front of the subject 'I,' ensuring that there is no dangling modifier. This structure establishes a clear connection between the action described in the introductory phrase and the subject performing the action, resulting in a grammatically correct sentence. Choice A, B, and D have dangling modifiers. In choice A, the phrase 'Walking down the street' should be followed by the noun it is describing to avoid the dangling modifier. Choice B has a dangling modifier as 'Having finished the report' does not have a clear subject to relate to. Choice D also has a dangling modifier as 'Exhausted from the hike' is not properly connected to the subject in the sentence.
