1. What is the best way to punctuate the dialogue, 'Are you coming?' she asked. 'Maybe,' I replied.

• A. 'Are you coming?' she asked? 'Maybe,' I replied.
• B. 'Are you coming?' she asked. 'Maybe,' I replied.
• C. 'Are you coming?' she asked, 'Maybe,' I replied.
• D. 'Are you coming?' she asked, 'Maybe,' I replied.

Correct answer: B

Rationale: The correct way to punctuate dialogue is to enclose each speaker's words in quotation marks. Additionally, the question mark should be placed inside the closing quotation mark of the question. In this case, the correct answer is B as it adheres to the punctuation rules for dialogue. Each character's dialogue is correctly enclosed in quotation marks, and the question mark is appropriately positioned inside the closing quotation mark of the question. Choice A is incorrect as the question mark is placed outside the closing quotation mark of the question. Choice C is incorrect as it uses a comma instead of a period after 'she asked.' Choice D is incorrect as it uses a comma instead of a period after 'she asked' and incorrectly places the comma inside the closing quotation mark of the question.

2. Based on the context of the passage, the reader can infer that this information is likely to appear in which of the following types of works?

• A. a scholarly paper
• B. a mystery
• C. a fictional story
• D. a biography

Correct answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.

3. What type of bond forms between elements when they share electrons?

• A. Covalent bond
• B. Ionic bond
• C. Metallic bond
• D. Hydrogen bond

Correct answer: A

Rationale: The correct answer is A: Covalent bond. In a covalent bond, atoms share electrons, leading to the creation of a strong attraction that holds them together. This type of bond is characterized by the sharing of electron pairs between atoms, resulting in the formation of molecules. Choice B, Ionic bond, involves the transfer of electrons from one atom to another, creating charged ions that attract each other. Choice C, Metallic bond, refers to the sharing of electrons among a sea of delocalized electrons in a metal structure. Choice D, Hydrogen bond, is a weak electrostatic attraction between a hydrogen atom and an electronegative atom like oxygen or nitrogen, not involving the sharing of electrons.

4. What happens when an atom loses an electron?

• A. It forms a molecule.
• B. It gains a positive charge and becomes an ion.
• C. It alters its elemental identity.
• D. No change occurs; it remains neutral.

Correct answer: B

Rationale: When an atom loses an electron, it gains a positive charge and becomes an ion. This occurs because the number of protons in the atom exceeds the number of electrons, leading to a positive charge. Therefore, the atom undergoes a transformation into an ion by losing an electron. Choice A is incorrect because losing an electron does not result in the formation of a molecule, as molecules are made up of bonded atoms. Choice C is incorrect because losing an electron does not change the fundamental identity of the atom; it only changes its charge. Choice D is incorrect because losing an electron causes the atom to become positively charged, altering its neutrality.

5. What is the SI unit of measurement for momentum?

• A. Newton (N)
• B. Kilogram-meter per second (kg·m/s)
• C. Joule (J)
• D. Newton-second (N·s)

Correct answer: B

Rationale: The correct SI unit of measurement for momentum is kilogram-meter per second (kg·m/s). Momentum is a vector quantity that is calculated by multiplying an object's mass (in kilograms) by its velocity (in meters per second), resulting in the unit kg·m/s. This unit represents the quantity of motion an object possesses, taking into account both the mass and velocity of the object. Choice A, Newton (N), is the unit of force, not momentum. Choice C, Joule (J), is the unit of energy, not momentum. Choice D, Newton-second (N·s), is the unit of impulse, not momentum.
