1. Which of the following words fits best in the sentence below? ___________ she is the youngest member of her class, Octavia is taller than her classmates.

• A. Despite
• B. Since
• C. Although
• D. Provided

Correct answer: C

Rationale: The word 'Although' is the correct choice as it is used to introduce a contrast between two ideas. In this sentence, it highlights the unexpected nature of Octavia being taller than her classmates despite being the youngest member of her class. This conjunction effectively conveys the discrepancy between her age and height in the context of the sentence. Choice A ('Despite') indicates a contradiction or contrast but does not capture the nuance of unexpectedness present in the sentence. Choice B ('Since') implies a causal relationship, which is not the intended meaning. Choice D ('Provided') suggests a condition or stipulation, which is not suitable for the context of the sentence. Therefore, 'Although' is the most appropriate choice.

2. How can the reaction rate of a chemical reaction be increased?

• A. Increase the temperature
• B. Increase the surface area
• C. Increase the concentration of reactants
• D. Add a catalyst

Correct answer: A

Rationale: To increase the reaction rate of a chemical reaction, one effective method is to increase the temperature. Raising the temperature provides more energy to the reacting particles, enabling them to collide more frequently and with higher energy, leading to an increase in the reaction rate. While increasing the surface area, concentration of reactants, and adding a catalyst are strategies that can also enhance the reaction rate, raising the temperature has the most direct and immediate impact. Increasing the surface area allows for more contact between reactants, increasing the concentration provides more reactant particles to collide, and adding a catalyst lowers the activation energy required for the reaction to occur. However, these methods may not have as immediate and significant an effect as increasing the temperature.

3. What type of reaction involves atoms attempting to achieve stable electron configurations?

• A. Chemical
• B. Nuclear
• C. Physical
• D. Mechanical

Correct answer: A

Rationale: In a chemical reaction, atoms interact to achieve stable electron configurations through the formation of new chemical bonds or the breaking of existing ones. This process aims to reach a more stable state by filling or emptying electron orbitals, leading to the formation of new substances with more stable configurations. Choice B, nuclear reactions, involve changes in the atomic nucleus rather than electron configurations. Choice C, physical reactions, involve changes in physical state or appearance without changing the chemical makeup. Choice D, mechanical reactions, do not involve the rearrangement of electrons to achieve stable configurations.

4. Select the word or phrase that makes this sentence grammatically correct: '____ screaming took the shopkeeper by surprise.'

• A. We
• B. They
• C. Them
• D. Our

Correct answer: D

Rationale: In this sentence, 'Our' is the possessive pronoun that correctly indicates possession, making the sentence grammatically correct. The sentence implies that the screaming belonged to a group that includes the shopkeeper. Therefore, 'Our' is the appropriate choice. The other options ('We,' 'They,' 'Them') are incorrect as they do not convey possession as required in the sentence.

5. Which statement would not be inferred by the reader in the passage about MRSA?

• A. Hospitals may soon limit the spread of infection with a new textile.
• B. MRSA begins by infecting the skin.
• C. You are most likely to contract MRSA in a crowded location.
• D. Used clothing stores may harbor MRSA.

Correct answer: D

Rationale: The correct answer is D: 'Used clothing stores may harbor MRSA.' This statement is not supported by the passage. The passage mentions the spread of MRSA in hospitals, gyms, locker rooms, swimming pools, and other settings with frequent human contact, but it does not mention used clothing stores as a common location for MRSA. Therefore, it is an unlikely inference. Choice A is supported by the passage as it discusses the development of a new textile to halt the spread of hospital-associated MRSA. Choice B is also supported as the passage mentions MRSA as a skin infection. Choice C is supported by the passage as it states that MRSA has become ubiquitous in settings with frequent human contact.
