1. Select the phrase or clause that is misplaced in the following sentence: I noticed a number of workers from my car window who were repairing the road alongside the mall.

• A. of workers
• B. from my car window
• C. who were repairing the road
• D. alongside the mall

Correct answer: A

Rationale: The phrase 'of workers' is misplaced in the sentence because the preposition 'of' is unnecessary and disrupts the flow of the sentence. It creates redundancy as 'a number of workers' can be simplified to 'workers.' Removing this unnecessary prepositional phrase would make the sentence clearer and more concise. Choice B 'from my car window' is correctly placed as it provides context on where the observation was made. Choice C 'who were repairing the road' and Choice D 'alongside the mall' are essential parts of the sentence providing details about the workers' activity and location, respectively.

2. The doctor said he wanted to try other things before attempting an __________ procedure.

• A. Internal
• B. Painful
• C. Experimental
• D. Expensive

Correct answer: C

Rationale: The term 'invasive' refers to a procedure that involves entering the body, usually with a medical instrument or device. In the context provided, the doctor wants to try other non-invasive or less invasive options before resorting to an invasive procedure. 'Experimental' means untested or not yet proven to be effective, which aligns with the idea of exploring alternative methods before considering a more invasive approach. Choices A, B, and D are incorrect because they do not relate to the context of trying alternative procedures that are different from invasive ones.

3. Which type of blood vessel carries blood back to the heart?

• A. Arteries
• B. Capillaries
• C. Veins
• D. Lymphatic vessels

Correct answer: C

Rationale: Veins are the blood vessels that carry deoxygenated blood back to the heart, except for the pulmonary veins which carry oxygenated blood from the lungs. Arteries carry oxygenated blood away from the heart. Capillaries facilitate the exchange of nutrients and gases between the blood and tissues but do not specifically carry blood back to the heart. Lymphatic vessels are part of the lymphatic system responsible for immune function and do not directly carry blood back to the heart. Therefore, the correct answer is veins.

4. The anterior chamber of the eye lies between the ___________.

• A. iris and lens
• B. lens and retina
• C. cornea and iris
• D. retina and optic nerve

Correct answer: A

Rationale: The anterior chamber of the eye is the fluid-filled space located between the cornea and the iris in the front part of the eye. It contains aqueous humor and helps maintain intraocular pressure. The space between the iris and the lens is known as the anterior chamber, making option A, 'iris and lens,' the correct choice. Options B, C, and D are incorrect because they do not describe the correct anatomical location of the anterior chamber.

5. What is the primary function of red blood cells?

• A. Clotting blood
• B. Transporting oxygen
• C. Fighting infection
• D. Carrying hormones

Correct answer: B

Rationale: The primary function of red blood cells, also known as erythrocytes, is to transport oxygen from the lungs to the body's tissues and organs. This is essential for cellular respiration and overall body functions. Red blood cells do not play a role in clotting blood, fighting infection, or carrying hormones. Choice A is incorrect because clotting blood is primarily done by platelets and other components of blood. Choice C is incorrect as fighting infection is a function mainly carried out by white blood cells. Choice D is incorrect because carrying hormones is primarily attributed to proteins like albumin and specific hormone-carrying proteins.
