1. Which muscle in the shoulder is the deltoid?

A. dendrite
B. delphic
C. deltoid
D. dentate

Correct answer: C

Rationale: The deltoid muscle is located in the shoulder area. It is a rounded, triangular muscle that covers the shoulder joint and is responsible for lifting the arm and providing shoulder stability. The other options provided, dendrite, delphic, and dentate, are not muscles in the shoulder region.

2. What is the meaning of incorrigible?

A. Curable
B. Incurable
C. Treatable
D. Temporary

Correct answer: B

Rationale: The correct answer is B: 'Incurable.' Incorrigible refers to something or someone that is beyond correction or incurable. It implies a persistent behavior or trait that is difficult or impossible to change. Choice A, 'Curable,' is incorrect because incorrigible means the opposite - not capable of being cured. Choice C, 'Treatable,' is incorrect because incorrigible implies a condition that is resistant to treatment. Choice D, 'Temporary,' is incorrect as incorrigible suggests a long-lasting or permanent state, not something temporary.

3. What is the best description of the word 'suppress'?

A. stop
B. push up
C. release
D. strain

Correct answer: A

Rationale: The correct answer is A: 'stop.' 'Suppress' means to stop or hold back something. Choice B, 'push up,' is incorrect as it does not accurately reflect the meaning of 'suppress.' Choice C, 'release,' is incorrect as it is the opposite of 'suppress.' Choice D, 'strain,' is also incorrect as it does not capture the meaning of 'suppress.'

4. What is the term for the lower surface of a structure?

A. Inferior
B. Transverse
C. Dorsal
D. Ventral

Correct answer: D

Rationale: The term for the lower surface of a structure is 'ventral.' 'Ventral' is used in anatomy to describe the front or lower surface of an organism or structure. In this context, 'inferior' (choice A) is not the correct term as it generally refers to something being below or lower in position but not specifically the lower surface of a structure. 'Transverse' (choice B) refers to a crosswise direction, not the lower surface. 'Dorsal' (choice C) is the term used for the upper or back surface of an organism or structure, opposite to the ventral surface.

5. Which of the following sentences is written in the passive voice?

A. The homework was completed by the student
B. The student completed the homework
C. The teacher is grading the papers
D. The store opens at 9 AM

Correct answer: A

Rationale: The correct answer is A: 'The homework was completed by the student.' This sentence is in the passive voice because the subject (homework) is being acted upon by the student. In passive voice constructions, the subject receives the action rather than performing it. Choices B, C, and D are in active voice where the subject performs the action. In choice B, 'The student completed the homework,' the subject (student) is the one performing the action of completing the homework.
