1. Fill in the blank with the correct subordinating conjunction: '... the class was difficult, Allison passed with flying colors.'

• A. If
• B. Since
• C. Because
• D. Although

Correct answer: D

Rationale: The correct conjunction is 'Although.' In this sentence, there is a contrast being made between the difficulty of the class and Allison's success, indicating that despite the class being difficult, she excelled. 'If' implies a condition, 'Since' indicates a reason, and 'Because' shows causation, which do not fit the context of the sentence where a contrast is being expressed.

2. Differentiate between gene therapy and genetic engineering in the context of human intervention.

• A. Gene therapy aims to modify existing genes within body cells, while genetic engineering manipulates genes in embryos to be passed on to offspring.
• B. Gene therapy focuses on treating genetic diseases, while genetic engineering enhances desirable traits or eliminates undesirable ones.
• C. Both involve directly altering the DNA sequence, but gene therapy targets somatic cells and genetic engineering modifies germline cells.
• D. There is no fundamental difference; both terms are synonymous.

Correct answer: B

Rationale: A) Incorrect. Gene therapy does aim to modify existing genes within body cells, but genetic engineering does not necessarily manipulate genes in embryos to be passed on to offspring. Genetic engineering can involve modifying genes in any type of cell, not just embryos. B) Correct. Gene therapy is a medical intervention that aims to treat genetic diseases by correcting or replacing faulty genes within an individual's body cells. On the other hand, genetic engineering involves modifying genes to enhance specific traits or eliminate undesirable ones, often in the context of agriculture or biotechnology. C) Incorrect. While both gene therapy and genetic engineering involve altering DNA sequences, the distinction lies in the target cells. Gene therapy targets somatic cells (non-reproductive cells), while genetic engineering typically involves modifying germline cells (reproductive cells that can pass on genetic changes to offspring). D) Incorrect. There is

3. Which hormone, produced by the pancreas, is released in response to low blood sugar levels and stimulates the release of glucose into the bloodstream?

• A. Insulin
• B. Glucagon
• C. Cortisol
• D. Thyroxine

Correct answer: B

Rationale: Glucagon is the hormone produced by the pancreas that is released in response to low blood sugar levels. It acts to stimulate the release of glucose into the bloodstream by promoting the breakdown of glycogen in the liver. Insulin, conversely, is released in response to high blood sugar levels and promotes the uptake of glucose by cells. Cortisol is a steroid hormone produced by the adrenal glands that regulates metabolism and the immune response. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism but is not involved in responding to low blood sugar levels.

4. Every morning we would wake up, eat breakfast, and break camp. Which of the following is the correct revision for the sentence?

• A. NO CHANGE
• B. we would wake up, eat breakfast, and break camp.
• C. would we wake up, eat breakfast, and break camp?
• D. we are waking up, eating breakfast, and breaking camp.

Correct answer: B

Rationale: The correct answer is B: 'we would wake up, eat breakfast, and break camp.' The original sentence is a list of actions in the past, so the verb 'break' should also be in the past tense to maintain consistency. Choice A is incorrect because 'broke' is incorrect in this context. Choice C is a question format and does not fit the original sentence structure. Choice D changes the tense to present progressive, which does not match the past tense context of the sentence.

5. Which of the following is NOT a state of matter?

• A. Solid
• B. Liquid
• C. Gas
• D. Superfluid

Correct answer: D

Rationale: The correct answer is 'Superfluid.' Superfluid is not considered a traditional state of matter. It is a unique phase of matter that displays zero viscosity and flows without losing kinetic energy. Solids, liquids, and gases are the three classical states of matter distinguished by their physical properties and structures. Therefore, choices A, B, and C are considered states of matter, while choice D, superfluid, is not.
