1. Which of the following is the independent variable in the equation below? f(t)=4t+9

• A. f
• B. 9
• C. t
• D. 4

Correct answer: C

Rationale: The independent variable in a function is the variable that is being manipulated or changed to obtain different values. In the equation f(t) = 4t + 9, the variable 't' is the independent variable. It is the variable that the function f(t) depends on, and changing its value will result in different outputs for the function. The other choices, 'f', '9', and '4', are not the independent variable as they do not represent the variable that is being manipulated to determine the function's output.

2. Which organ is primarily responsible for detoxification in the body?

• A. Kidney
• B. Liver
• C. Lung
• D. Heart

Correct answer: B

Rationale: The liver is the primary organ responsible for detoxifying chemicals and metabolizing drugs in the body. It plays a crucial role in breaking down toxins, filtering blood, and producing bile, making it essential for overall detoxification processes. The kidney primarily filters waste and excess substances from the blood to form urine. Lungs are responsible for gas exchange, not detoxification. The heart is responsible for pumping blood and does not play a direct role in detoxification processes.

3. Which word completes the sentence: 'Despite the storm, the concert ____ went on.'

• A. nevertheless
• B. however
• C. therefore
• D. nonetheless

Correct answer: D

Rationale: 'Nonetheless' is the correct word to complete the sentence as it emphasizes the continuation of the concert despite the contrary circumstance. 'Nevertheless' and 'however' are synonyms and indicate contrast rather than continuity. 'Therefore' implies a conclusion or result, which is not fitting in this context.

4. Which of the following lists of joint types is in the correct order for increasing amounts of permitted motion (least mobile to most mobile)?

• A. Hinge, condyloid, saddle
• B. Saddle, hinge, condyloid
• C. Saddle, condyloid, hinge
• D. Hinge, saddle, condyloid

Correct answer: A

Rationale: The correct order of joint types, from least mobile to most mobile, is hinge, condyloid, saddle. A hinge joint allows movement in one plane (like a door hinge), a condyloid joint allows movement in two planes but not rotation (like the wrist), and a saddle joint allows movement in multiple directions (like the thumb). Choice A, 'Hinge, condyloid, saddle,' is the correct sequence as it accurately represents the order of increasing permitted motion in joints. Choices B, C, and D are incorrect because they do not follow the correct order of joint types from least mobile to most mobile as required by the question.

5. What type of sentence is the following example? Although I wished it were summer, I accepted the change of seasons, and I started to appreciate the fall.

• A. Compound
• B. Simple
• C. Complex
• D. Compound-Complex

Correct answer: C

Rationale: This sentence is a complex sentence because it consists of an independent clause ('I accepted the change of seasons, and I started to appreciate the fall') and a dependent clause ('Although I wished it were summer'). The dependent clause cannot stand alone as a complete sentence and relies on the independent clause to make sense. Choice A (Compound) is incorrect because a compound sentence requires two independent clauses joined by a coordinating conjunction. Choice B (Simple) is incorrect as it does not account for the presence of both independent and dependent clauses. Choice D (Compound-Complex) is incorrect as it would require at least two independent clauses and one or more dependent clauses.
