1. In a scientific investigation, what is the first step?

• A. Analysis of results
• B. Drawing conclusions
• C. Formation of hypothesis
• D. Performing the experiment

Correct answer: C

Rationale: The correct answer is C: Formation of hypothesis. In a scientific investigation, forming a hypothesis is the initial step. A hypothesis is an educated guess or prediction based on existing knowledge and observations. It helps guide the experiment and provides a direction for the research process. Without a hypothesis, there is no specific aim or goal for the experiment. Choices A, B, and D are incorrect because they occur after the formation of a hypothesis. Analysis of results and drawing conclusions typically come after the experiment has been conducted, while performing the experiment is done to test the hypothesis formed at the beginning of the investigation.

2. Which of the following is equal to 0.16 inches?

• A. 0.016 inches
• B. 0.16 inches
• C. 1.6 inches
• D. 16 inches

Correct answer: B

Rationale: The correct answer is B: 0.16 inches. This value is already in its simplest form and represents sixteen one-hundredths of an inch. Choice A, 0.016 inches, is incorrect as it represents sixteen thousandths of an inch, not the given value. Choice C, 1.6 inches, is incorrect as it represents one and six-tenths inches, which is larger than the given value. Choice D, 16 inches, is incorrect as it represents sixteen inches, which is significantly larger than the given value of 0.16 inches.

3. Based on the following passage, which of the following scenarios is correct?

• A. The writer is a professional in a business environment.
• B. The writer is a researcher writing for a scientific journal.
• C. The writer is a student writing a first draft of a paper.
• D. The writer is an author of literature.

Correct answer: B

Rationale: The passage uses precise, technical language typical of scientific writing, indicating the writer is a researcher. Choice A is incorrect as the passage does not reflect a business context. Choice C is incorrect as there is no indication that the writer is a student or in an academic setting. Choice D is incorrect as the content of the passage does not align with literature or creative writing.

4. Urine, the liquid waste product of the body, travels from the kidneys to the bladder through tubes called:

• A. Ureters
• B. Urethra
• C. Nephrons
• D. Renal pelvis

Correct answer: A

Rationale: The correct answer is 'Ureters.' Ureters are tubes that connect each kidney to the bladder. They transport urine from the kidneys to the bladder for storage before excretion. The urethra, which is not the correct answer, is responsible for carrying urine from the bladder out of the body. Nephrons, another incorrect choice, are microscopic units within the kidneys that filter blood and produce urine. The renal pelvis, also an incorrect choice, is a structure in the kidney where urine collects before moving into the ureters for further passage to the bladder.

5. Identify the incorrect usage of punctuation in the following sentence: 'The children, eager to play, ran outside; it was a beautiful day.'

• A. comma after 'children'
• B. comma after 'play'
• C. period after 'outside'
• D. no errors

Correct answer: C

Rationale: The sentence contains two independent clauses that should be separated by a semicolon or period, not a comma. The incorrect punctuation is the period after 'outside.' A period or semicolon is needed to correctly separate the two independent clauses. The comma after 'children' and 'play' are correctly used to set off non-essential participial phrases. Choice D is incorrect as there is a punctuation error in the sentence.
