English Grammar

1. What is the main function of transition words and phrases in writing?

Correct answer: C

Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.

2. Which of the following is NOT a type of vaccine?

Correct answer: D

Rationale: Rationale: A) Live attenuated vaccine: This type of vaccine contains a weakened form of the virus or bacteria that causes the disease. When administered, it stimulates an immune response without causing the disease itself. B) Toxoid vaccine: Toxoid vaccines are made from toxins produced by bacteria that have been inactivated. They stimulate the immune system to produce antibodies against the toxin, providing immunity against the disease. C) Conjugate vaccine: Conjugate vaccines are made by combining a weak antigen with a strong antigen to enhance the immune response. They are commonly used to protect against bacterial infections. D) Antibiotic: Antibiotics are medications used to treat bacterial infections by killing or inhibiting the growth of bacteria. They are not a type of vaccine but rather a class of antimicrobial drugs. Therefore, the correct answer is D) Antibiotic, as it is not a type of vaccine.

3. The diaphragm is a dome-shaped muscle that plays a crucial role in breathing. When it contracts, what happens?

Correct answer: B

Rationale: The diaphragm is a dome-shaped muscle located beneath the lungs. When it contracts, it moves downward, creating more space in the chest cavity. This downward movement of the diaphragm allows the lungs to expand, which lowers the air pressure inside the lungs. As a result, air from the outside rushes in to equalize the pressure, leading to inhalation. Therefore, when the diaphragm contracts, it facilitates the intake of air into the lungs, making option B, 'The lungs expand to allow air intake,' the correct answer.

4. What is the function of the pituitary gland?

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

5. What is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning?

Correct answer: C

Rationale: The correct answer is C: Cerebrum. The cerebrum is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning. It is divided into two hemispheres (left and right) and is associated with intelligence, creativity, reasoning, and problem-solving abilities. The brainstem (option A) is responsible for basic life functions like breathing and heart rate. The cerebellum (option B) is involved in coordination and balance. The thalamus (option D) acts as a relay station for sensory information. Therefore, the cerebrum is the most appropriate choice for the part of the brain responsible for higher cognitive functions.

6. What is the difference between a pure substance and a mixture?

Correct answer: A

Rationale: Rationale: - Pure substances have a definite and constant composition, meaning they are made up of only one type of atom or molecule. This composition does not vary. - Mixtures, on the other hand, are composed of two or more substances physically combined. The components of a mixture can be present in varying proportions, leading to a variable composition. - Option A correctly distinguishes between pure substances and mixtures based on the fixed composition of pure substances and the variable composition of mixtures.
