1. What is the most visible part of the ear?

• A. Ear canal
• B. Cochlea
• C. Organ of Corti
• D. Pinna

Correct answer: D

Rationale: The pinna, also known as the auricle, is the most visible part of the ear. Its external shape and location make it easily noticeable on the side of the head. The pinna helps in capturing sound waves and directing them into the ear canal, where the sound transmission process begins. The other structures listed, the Organ of Corti, Cochlea, and Ear canal, are essential parts of the ear involved in hearing and sound processing, but they are not as visibly prominent as the pinna. Therefore, the correct answer is the pinna because of its external visibility and role in capturing sound waves.

2. Choose the meaning of the word 'disregard' in the following sentence: 'He chose to disregard the warnings.'

• A. Have no opinion about
• B. Pay attention to
• C. Care for
• D. Ignore

Correct answer: D

Rationale: The correct meaning of 'disregard' in the sentence provided is 'to ignore.' When someone disregards something, they are choosing not to pay attention to it or consider it important. Choice A, 'Have no opinion about,' is incorrect as disregard implies actively ignoring something rather than having no opinion. Choice B, 'Pay attention to,' is the opposite of disregard. Choice C, 'Care for,' is also the opposite of disregard, as caring for something implies giving it importance and attention.

3. Why can animal cells use a contractile ring but plant cells cannot?

• A. Plant cells can use both methods to divide
• B. Animal cells divide faster, requiring them to pinch apart
• C. Plant cells are too rigid to use a contractile ring
• D. N/A

Correct answer: C

Rationale: Plant cells have a rigid cell wall surrounding them, which prevents them from using a contractile ring for cell division. The rigid cell wall requires plant cells to form a cell plate during cell division instead of pinching apart like animal cells with a contractile ring. Choice A is incorrect because plant cells cannot use a contractile ring due to their rigid cell wall. Choice B is incorrect as the speed of cell division is not the primary reason for the difference in cell division mechanisms between plant and animal cells. Choice D is not applicable as plant cells indeed have a specific limitation in using a contractile ring for cell division.

4. Choose the meaning of the word 'inquest' in the following sentence: 'Many interesting discoveries were made at the inquest.'

• A. Tryout
• B. Intake
• C. Autopsy
• D. Checkup

Correct answer: C

Rationale: The word 'inquest' typically refers to a legal investigation or inquiry, especially into the cause of someone's death. In this context, an 'inquest' is associated with conducting an autopsy to determine the cause of death. Choices A, B, and D are incorrect. A 'tryout' refers to a test or trial, 'intake' relates to the process of taking something in, such as food or air, and a 'checkup' is a general medical examination.

5. If a package of 10 pencils is divided between every 2 students in a class with 20 students, how many pencils are needed?

• A. 20
• B. 40
• C. 80
• D. 100

Correct answer: D

Rationale: If 20 students are divided into pairs, there would be 10 pairs in total (20 students / 2 = 10 pairs). Since each pair receives 10 pencils, the total number of pencils needed is calculated by multiplying the number of pairs (10 pairs) by the number of pencils each pair receives (10 pencils per pair), resulting in 100 pencils required. Therefore, the correct answer is 100 pencils. Choices A, B, and C are incorrect because they do not consider the correct pairing of students or the total number of pencils needed for each pair.
