1. Which of the following sentences correctly uses a hyphen?

A. Last year, many of the players felt unsure of the coach's methods.
B. Some of the furniture she selected seemed a bit over-the-top for the space.
C. Henry is a beagle-mix and is ready for adoption this weekend.
D. Geena works to maintain a good relationship with her ex-husband to the benefit of their children.

Correct answer: C

Rationale: The correct usage of a hyphen is seen in sentence C, 'Henry is a beagle-mix and is ready for adoption this weekend.' The hyphen is used in 'beagle-mix' to link the two words together to describe Henry's breed accurately. Choice A contains a comma incorrectly placed after 'Last year.' Choice B uses hyphens as dashes, which is incorrect. Choice D does not require a hyphen as there is no compound term or adjective that needs to be linked.

2. When light interacts with a perfectly smooth surface, like a mirror, the dominant interaction is:

A. Refraction
B. Diffraction
C. Total internal reflection
D. Specular reflection

Correct answer: D

Rationale: When light interacts with a perfectly smooth surface like a mirror, the dominant interaction is specular reflection. Specular reflection occurs when light rays are reflected off a smooth surface at the same angle as the incident angle, resulting in a clear and sharp reflection. Refraction, which involves the bending of light as it passes from one medium to another, is not the dominant interaction with a perfectly smooth surface. Diffraction, the bending of light waves around obstacles, is not the dominant interaction with smooth surfaces. Total internal reflection occurs when light is reflected back into a medium due to encountering a boundary at an angle greater than the critical angle, but it is not the dominant interaction on a perfectly smooth surface like a mirror.

3. Which of the following sentences shows the correct use of quotation marks?

A. "Grady asked Abe, 'Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?'"
B. Grady asked Abe, 'Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?'
C. Grady asked Abe, "Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?"
D. Grady asked Abe, "Did you know that an earthquake and a tsunami hit Messina, Italy, in 1908?"

Correct answer: C

Rationale: The correct use of quotation marks is in option C. In this option, the entire quoted sentence is enclosed within double quotation marks. This is the standard convention for punctuating direct speech in English. Option A has an incorrect placement of single and double quotation marks. Option B lacks opening double quotation marks for the spoken sentence. Option D incorrectly places the closing quotation mark outside the question mark, which is not the standard punctuation rule for quoted sentences.

4. What is the primary function of the lymphatic system?

A. Transporting oxygen and nutrients to cells
B. Carrying waste products away from tissues
C. Regulating body temperature
D. Producing red blood cells

Correct answer: B

Rationale: The primary function of the lymphatic system is to carry waste products away from tissues. Lymphatic vessels collect excess fluid, waste materials, and toxins from the body's tissues and transport them to the bloodstream for elimination. Choice A is incorrect because transporting oxygen and nutrients to cells is mainly the function of the circulatory system. Choice C is incorrect as regulating body temperature is primarily done by the body's thermoregulatory mechanisms. Choice D is incorrect because the production of red blood cells occurs in the bone marrow, not in the lymphatic system.

5. Which of the following is directly transcribed from DNA and represents the first step in protein synthesis?

A. siRNA
B. rRNA
C. mRNA
D. tRNA

Correct answer: C

Rationale: mRNA (messenger RNA) is directly transcribed from DNA in the nucleus during the process of transcription. It serves as a template for protein synthesis during translation in the cytoplasm. mRNA carries genetic information from the DNA to the ribosomes, where it determines the sequence of amino acids in a protein. Thus, mRNA represents the first step in protein synthesis as it carries the code from the DNA to be translated into a protein. Choice A, siRNA (small interfering RNA), is involved in post-transcriptional gene silencing and does not play a role in protein synthesis. Choice B, rRNA (ribosomal RNA), is a component of the ribosome and plays a structural and functional role in protein synthesis but is not directly transcribed from DNA. Choice D, tRNA (transfer RNA), is responsible for bringing amino acids to the ribosome during protein synthesis but is not directly transcribed from DNA.
