1. Janine was so nervous that she was surprisingly graceless and awkward on stage. What is the meaning of the word 'graceless' as used in the sentence below?

• A. Against fear
• B. Without religion
• C. Lacking elegance
• D. Full of caution

Correct answer: C

Rationale: The word 'graceless' in this context means lacking elegance or poise. Janine's nervousness caused her to act awkwardly and without the elegance one would typically expect on stage. Choices A, B, and D are incorrect. 'Against fear,' 'Without religion,' and 'Full of caution' do not accurately capture the meaning of 'graceless' in the given sentence.

2. Which of the following organs belongs to the digestive system?

• A. Spine
• B. Lungs
• C. Brain
• D. Stomach

Correct answer: D

Rationale: The correct answer is D: Stomach. The stomach is an organ of the digestive system. Its main function is to break down and digest food, allowing the nutrients to be absorbed into the body. The stomach secretes digestive enzymes and acids to help in the digestion process. Choices A, B, and C are incorrect as the spine, lungs, and brain are not part of the digestive system. The spine is part of the skeletal system, the lungs belong to the respiratory system, and the brain is part of the nervous system.

3. What structure in plant cells provides rigidity and support?

• A. Cell membrane
• B. Golgi apparatus
• C. Plastid
• D. Cell wall

Correct answer: D

Rationale: The correct answer is D, the cell wall. The cell wall is the structure in plant cells that provides rigidity and support. It is a tough, rigid structure located outside the cell membrane. Composed primarily of cellulose, the cell wall offers structural support to the cell, helping it maintain its shape and protect it from damage. The other choices, such as the cell membrane (choice A), Golgi apparatus (choice B), and plastid (choice C) do not provide rigidity and support to plant cells. The cell membrane is a selectively permeable barrier, the Golgi apparatus is involved in processing and packaging proteins, and plastids are organelles responsible for functions like photosynthesis and storage, but they do not provide the structural support that the cell wall does.

4. Which structure in the respiratory system is responsible for voice production?

• A. Pharynx
• B. Larynx
• C. Trachea
• D. Bronchi

Correct answer: B

Rationale: The correct answer is the larynx. The larynx, commonly referred to as the voice box, is responsible for voice production in the respiratory system. It contains vocal cords that vibrate to produce sound. The pharynx is a passage for food and air, the trachea is a tubular structure that carries air to and from the lungs, and the bronchi are the main airway passages in the lungs. Therefore, choices A, C, and D are incorrect as they do not play a direct role in voice production.

5. Xan was worried about the epidemic she heard about on the news. In the word 'epidemic,' the prefix 'epi-' most closely means:

• A. Badly
• B. On
• C. A lot
• D. A little

Correct answer: B

Rationale: The correct answer is 'B: On.' The prefix 'epi-' means 'on' or 'upon,' as seen in the word 'epidemic.' An epidemic refers to a situation where a disease spreads rapidly and affects many people. Choice 'A: Badly' is incorrect as it does not accurately represent the meaning of the prefix 'epi-.' Choices 'C: A lot' and 'D: A little' are also incorrect as they are not related to the prefix 'epi-' in the context of the word 'epidemic.'
