1. The lymphatic system works closely with which other body system to fight infections?

• A. Respiratory system
• B. Digestive system
• C. Immune system
• D. Nervous system

Correct answer: C

Rationale: The lymphatic system and the immune system work closely together to fight infections. The lymphatic system aids the immune system by circulating white blood cells, a crucial component in combating pathogens, throughout the body. This collaboration helps identify and eliminate harmful invaders to maintain the body's health and well-being. Choice A (Respiratory system) is incorrect because while it plays a role in oxygen exchange and removing carbon dioxide, it is not primarily responsible for fighting infections. Choice B (Digestive system) is incorrect as its main functions involve breaking down food and absorbing nutrients, not directly fighting infections. Choice D (Nervous system) is incorrect because its primary role is in transmitting signals throughout the body and controlling bodily functions, not in fighting infections.

2. Which of the following statements is true about the dependent variable?

• A. A factor that remains constant during the experiment
• B. A factor with data typically plotted on the x-axis
• C. A factor that is measured during an experiment
• D. A factor with data typically plotted on the y-axis

Correct answer: C

Rationale: The correct answer is C. The dependent variable is the factor that is being measured or observed in an experiment. It is the outcome that is affected by changes in the independent variable. In graphical representations, the dependent variable is usually plotted on the y-axis, not the x-axis. Choice A is incorrect because a factor that remains constant is referred to as a constant, not a dependent variable. Choice B is incorrect as the independent variable's data is typically plotted on the x-axis. Choice D is incorrect because the dependent variable's data is usually plotted on the y-axis. Therefore, choice C accurately describes the dependent variable.

3. Which of the following options is correctly punctuated?

• A. The runaway truck, which had been parked on a steep hill, swerved and teetered before jumping a curb and slamming into a tree.
• B. The runaway truck which had been parked on a steep hill swerved and teetered before jumping a curb and slamming into a tree.
• C. The runaway truck, which had been parked on a steep hill, swerved and teetered before jumping a curb and slamming into a tree.
• D. The runaway truck which had been parked on a steep hill, swerved and teetered before jumping a curb and slamming into a tree.

Correct answer: A

Rationale: The correct answer is A. The sentence correctly uses commas to set off the non-essential clause 'which had been parked on a steep hill.' The use of commas before and after the clause helps to distinguish it as additional information that could be omitted without changing the essential meaning of the sentence. Choices B, C, and D lack appropriate punctuation to set off the non-essential clause, making them incorrect. In these options, the absence of commas or the placement of commas incorrectly within the sentence affects the clarity and structure of the sentence, violating punctuation rules for non-essential clauses.

4. What are the three layers of the skin?

• A. Epidermis, dermis, subdermis
• B. Epidermis, dermis, hypodermis
• C. Dermis, subdermis, hypodermis
• D. Epidermis, dermis, adipose layer

Correct answer: B

Rationale: The correct answer is B: Epidermis, dermis, hypodermis. The three layers of the skin are the epidermis (outer layer), dermis (middle layer), and hypodermis (inner layer of fat and connective tissue). The hypodermis is also known as the subcutaneous tissue and is primarily composed of adipose (fat) tissue, providing insulation and padding to the body. Choice A is incorrect as 'subdermis' is not a recognized layer of the skin. Choice C is incorrect as 'dermis' is the middle layer, not the outer layer. Choice D is incorrect as the layer below the dermis is the hypodermis, not specifically an 'adipose layer.'

5. Identify the type of error in the sentence, 'They went to the store, bought groceries, then went home.'

• A. Run-on sentence
• B. Comma splice
• C. Dangling modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The given sentence combines multiple independent clauses without appropriate punctuation or conjunctions, creating a run-on sentence. A run-on sentence occurs when two or more independent clauses are joined without the necessary punctuation or coordination. In this case, the sentence lacks the proper conjunction or punctuation between 'store' and 'bought,' resulting in a run-on sentence. Choice B, 'Comma splice,' is incorrect because a comma splice involves joining two independent clauses with just a comma, which is not the case in the given sentence. Choice C, 'Dangling modifier,' is incorrect as there are no misplaced modifiers in the sentence. Choice D, 'Subject-verb agreement,' is also incorrect as the error in the sentence does not involve subject-verb agreement but rather the incorrect combination of independent clauses.
