1. What does it mean if a theory is obsolete?

• A. Advanced
• B. Outdated
• C. Useful
• D. Innovative

Correct answer: B

Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice. Choice A, 'Advanced,' is incorrect as it implies progression rather than obsolescence. Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated. Choice D, 'Innovative,' is incorrect as it suggests newness and originality, which are opposite to being obsolete.

2. The plumber used a tube to navigate through the curved pipe. What type of tube would be most suitable for this task?

• A. Solid
• B. Rigid
• C. Flexible
• D. Perforated

Correct answer: C

Rationale: A flexible tube would be appropriate for navigating through a curved pipe as it can bend and maneuver easily within the pipe's shape. This flexibility allows the plumber to access and address any blockages or issues efficiently. Solid and rigid tubes would be challenging to use in a curved pipe due to their lack of flexibility, making navigation difficult. Perforated tubes, with holes, are not typically used for this purpose and are more suited for specific applications like drainage systems.

3. What is the result of adding 7/21 + 10/21?

• A. 17/21
• B. 15/21
• C. 9/21
• D. 10/21

Correct answer: A

Rationale: When adding fractions with the same denominator, you simply add the numerators while keeping the denominator the same. In this case, 7/21 + 10/21 = 17/21. Therefore, the correct answer is A. Choice B (15/21) is incorrect because it adds the numerators incorrectly. Choice C (9/21) is incorrect as it does not reflect the sum of the fractions provided. Choice D (10/21) is also incorrect as it does not represent the correct sum of the two fractions.

4. Why do cells need to use exocytosis?

• A. To obtain energy
• B. To defend against invaders
• C. To remove waste products
• D. To undergo division

Correct answer: C

Rationale: Cells need to use exocytosis to remove waste products from the cell. Exocytosis is a process where cells release molecules or substances outside the cell by fusing vesicles with the cell membrane. This process is crucial for maintaining cellular homeostasis by efficiently eliminating waste materials. Choices A, B, and D are incorrect because exocytosis is specifically involved in the expulsion of molecules, not for obtaining energy, defending against invaders, or cell division.

5. Select the word that makes this sentence grammatically correct: 'While he was an apprentice, Steve ____ a great deal of time in the studio.'

• A. spends
• B. spent
• C. spended
• D. spend

Correct answer: B

Rationale: 'Spent' is the correct past tense of 'spend.' In this sentence, the action of spending time in the studio already happened while Steve was an apprentice, requiring the past tense 'spent.' 'Spends' is present tense, 'spended' is not a valid word, and 'spend' is present tense without matching the past context of the sentence.
