1. Imagine you have an element with atomic number 20 and mass number 40. How many neutrons does it have?

• A. 20
• B. 40
• C. 10
• D. 20

Correct answer: C

Rationale: - The atomic number (Z) represents the number of protons in an atom. In this case, the atomic number is 20. - The mass number (A) represents the total number of protons and neutrons in an atom. In this case, the mass number is 40. - To find the number of neutrons, you subtract the atomic number from the mass number: Neutrons = Mass number - Atomic number. - Neutrons = 40 - 20 = 20. - Therefore, the element with atomic number 20 and mass number 40 has 20 neutrons.

2. Which of the following correctly completes the sentence? 'A childhood reading of Tales from Shakespeare permanently _____ Helene’s interest in studying the Great Bard.'

• A. piqued
• B. peaked
• C. peked
• D. peeked

Correct answer: A

Rationale: The word 'piqued' means to stimulate or arouse interest or curiosity. In this context, the sentence is referring to Helene’s interest in Shakespeare being stirred or awakened, which makes 'piqued' the correct word. Both 'peaked' and 'peeked' have different meanings (reaching the highest point and looking quickly, respectively) that do not fit the sentence. 'Peked' is not a valid word and does not make sense in the context of the sentence. Therefore, option 'A' is the correct choice.

3. Identify the type of clause in the sentence: 'While the rain poured, they huddled inside for warmth.'

• A. Main clause
• B. Subordinate clause
• C. Appositive clause
• D. Noun clause

Correct answer: B

Rationale: The clause 'While the rain poured' is a subordinate clause because it cannot stand alone as a complete sentence and provides additional information about the main action 'they huddled inside'. Subordinate clauses typically begin with subordinating conjunctions like 'while', 'because', 'if', etc. They rely on the main clause for context and meaning. In this sentence, the main action is 'they huddled inside,' making 'While the rain poured' a subordinate clause. The other choices are incorrect: An appositive clause renames or explains a noun, a noun clause functions as a noun within a sentence, and a main clause can stand alone as a complete sentence.

4. If x represents the width of a rectangle and the length is six less than two times the width, which of the following expressions represents the length of the rectangle in terms of x?

• A. 2x-6
• B. 6-2x
• C. 6x-2
• D. 3x-4

Correct answer: A

Rationale: To find the expression representing the length of the rectangle in terms of x, we need to consider that the length is six less than two times the width. If we denote the width as x, the length can be expressed as 2x - 6. Therefore, the correct expression is 2x-6 (choice A). Choice B, 6-2x, represents the width subtracted from 6, not the length. Choice C, 6x-2, is not derived from the given information about the relationship between the width and length. Choice D, 3x-4, is not consistent with the relationship provided in the question.

5. What are the two main divisions of the skeletal system?

• A. Upper and lower body bones
• B. Axial and appendicular skeleton
• C. Long and short bones
• D. Compact and spongy bone

Correct answer: B

Rationale: The skeletal system is divided into two main divisions: the axial skeleton and the appendicular skeleton. The axial skeleton comprises the skull, vertebral column, and rib cage, providing structural support and protection for vital organs. On the other hand, the appendicular skeleton includes the bones of the upper and lower limbs, shoulder girdle, and pelvic girdle, facilitating movement and flexibility. The divisions are based on the location and function of the bones within the skeletal system, making choices A, C, and D incorrect as they do not represent the primary divisions of the skeletal system.
