• A. spiral

2. The student ___________ for the final exam.

• A. Was studying
• B. Didn’t study
• C. Studied hard
• D. Would have studied

Correct answer: A

Rationale: The correct answer is 'Was studying,' which is the past continuous form describing an action that was happening at a specific time in the past. Choice B, 'Didn’t study,' is incorrect because it's in simple past tense, not the continuous form required by the context. Choice C, 'Studied hard,' is incorrect as it lacks the continuous aspect required by the context. Choice D, 'Would have studied,' is in the wrong tense; it is a hypothetical past action, not an action in progress in the past.

3. The passage explicitly states?

• A. That the highest card within the 'trump' suit always wins the trick.
• B. That there is a pile of leftover cards that is placed in the middle of the game table.
• C. If a player cannot follow suit, they lose their turn to the next player.
• D. The Ace card is always the lowest card.

Correct answer: A

Rationale: The correct answer is A: 'That the highest card within the 'trump' suit always wins the trick.' The passage explicitly mentions that in the game of Bridge, if a player plays a card from the trump suit, it always wins the trick. This detail is clearly stated in the text, making it the correct choice. Choice B is incorrect as there is no mention of a pile of leftover cards in the passage. Choice C is incorrect as the passage does not state that a player loses their turn if they cannot follow suit; instead, they play any card. Choice D is incorrect as the passage states that the ace is high, not low.

4. Which organelle is responsible for detoxifying harmful substances in the cell?

• A. Endoplasmic Reticulum
• B. Lysosomes
• C. Peroxisomes
• D. Golgi Apparatus

Correct answer: C

Rationale: The correct answer is C, Peroxisomes. Peroxisomes are responsible for detoxifying harmful substances in the cell by breaking down fatty acids and producing hydrogen peroxide. This process helps protect the cell from damage caused by toxic substances. Choice A, Endoplasmic Reticulum, is involved in protein and lipid synthesis, not detoxification. Choice B, Lysosomes, contain enzymes for digestion and waste removal, not primarily detoxification. Choice D, Golgi Apparatus, is responsible for modifying, sorting, and packaging proteins for secretion, not detoxification.

5. Which type of blood cell is primarily responsible for fighting infections?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Plasma

Correct answer: B

Rationale: White blood cells, also known as leukocytes, play a crucial role in the immune system by primarily combating infections. These cells can identify and destroy pathogens, such as bacteria and viruses, helping the body defend against illnesses and maintain overall health. Red blood cells are responsible for oxygen transport, platelets aid in blood clotting, and plasma carries various components throughout the circulatory system, but none of these functions involve fighting infections like white blood cells do.
