1. During a scientific investigation, what is intentionally changed or manipulated?

• A. The dependent variable.
• B. The control.
• C. The hypothesis.
• D. The independent variable.

Correct answer: D

Rationale: During a scientific investigation, the independent variable is intentionally changed or manipulated by the researcher to observe its impact or effect on the dependent variable. The independent variable is the one being tested or studied to see how it influences the dependent variable. In contrast, the dependent variable is the outcome or response that is measured in an experiment and is expected to change as a result of the manipulation of the independent variable. Choices A, B, and C are not directly altered during a scientific investigation but play different roles in the research process. Therefore, the correct answer is D - the independent variable.

2. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

• A. Wheezing
• B. Difficulty breathing
• C. Chest tightness
• D. Fever

Correct answer: D

Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.

3. 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.

4. On Parents’ Day, a public holiday in the Democratic Republic of Congo, families celebrate parents’ both living and deceased. Which of the following punctuation marks is used incorrectly?

• A. the apostrophe in Parents’ Day
• B. the comma following Day
• C. the comma following Congo
• D. the apostrophe in parents’

Correct answer: B

Rationale: The comma following 'Day' is used incorrectly. Commas are typically not used after single-word identifiers like 'Day' in a sentence unless they are part of a list. In this case, the holiday is referred to as 'Parents’ Day,' where the apostrophe is used correctly to indicate possession. The comma following 'Day' is unnecessary and should be removed for proper punctuation. Choices A and D both use apostrophes correctly to indicate possession, so they are not incorrect. The comma following 'Congo' in choice C is necessary to set off the introductory phrase 'a public holiday in the Democratic Republic of Congo.' Therefore, the correct answer is B.

5. Which of the following is a thesis statement?

• A. While Abel Tasman is the first European credited with seeing New Zealand, James Cook is recognized for mapping the country.
• B. James Cook is recognized for mapping New Zealand.
• C. Abel Tasman was the first European to see New Zealand.
• D. New Zealand was first mapped by James Cook.

Correct answer: A

Rationale: Choice A is the correct answer as it presents a clear thesis statement by comparing the achievements of Abel Tasman and James Cook. It establishes the main argument of the text, which is a key characteristic of a thesis statement. Choice B is too specific and only focuses on James Cook without presenting an argument. Choice C simply states a historical fact without presenting an argument or comparison. Choice D, while related to the topic, does not establish a clear argument or comparison between individuals, making it an incorrect thesis statement.
