1. Which of the following statements offers a supporting argument for the passage's claim that many coastal islands are eroding?

• A. Recent hurricane seasons have been expensive.
• B. The Atlantic Basin is entering an active period.
• C. Louisiana has lost 2,000 square miles of coastal land.
• D. Barrier islands are the first line of defense against coastal storms.

Correct answer: C

Rationale: Statement C directly provides evidence of coastal land erosion by stating that Louisiana has lost a significant amount of coastal land area. This supports the passage's claim that many coastal islands are eroding. Choice A is incorrect because the expense of recent hurricane seasons does not directly relate to coastal land erosion. Choice B is incorrect as the active period of the Atlantic Basin does not specifically address coastal land erosion. Choice D, while related to coastal storms, does not directly support the claim that many coastal islands are eroding.

2. Which sentence correctly uses the colon?

• A. She had one wish: to visit Paris.
• B. She had: one wish to visit Paris.
• C. She had one: wish to visit Paris.
• D. She had one wish: visit Paris.

Correct answer: A

Rationale: The correct answer is A: "She had one wish: to visit Paris." A colon is used after a complete sentence to introduce a list, quotation, or explanation. In choice A, the colon is appropriately used after the complete sentence 'She had one wish' to introduce the explanation 'to visit Paris.' Choices B, C, and D incorrectly place the colon in positions that do not follow a complete sentence or do not properly introduce an explanation, making them grammatically incorrect.

3. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.

• A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer.
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional.
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals.
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures.

Correct answer: C

Rationale: Ionic bonds typically form between metals and non-metals, where one atom donates electrons (cation) and the other accepts electrons (anion). This results in the transfer of electrons. Metallic bonds, on the other hand, occur between metal atoms where electrons are shared among a sea of delocalized electrons, leading to the characteristic properties of metals like malleability and conductivity. Choice A is incorrect because ionic bonds involve electron transfer, not sharing. Choice B is incorrect as ionic bonds are strong, not weak, and are non-directional, while metallic bonds are strong and non-directional. Choice D is incorrect as ionic bonds do not form discrete molecules but rather a lattice structure, whereas metallic bonds form extended structures.

4. What is the cycle of infection?

• A. Reservoir host, means of exit, means of transmission, means of entrance, susceptible host
• B. Entry point, transmission, replication, exit, susceptible host
• C. Susceptible host, replication, transmission, entry, exit
• D. Transmission, replication, entry, exit, susceptible host

Correct answer: A

Rationale: The correct answer is A: 'Reservoir host, means of exit, means of transmission, means of entrance, susceptible host.' This cycle of infection involves the pathogen starting in a reservoir host, exiting through a means, being transmitted to another host, entering the new host through a means, and ultimately infecting the susceptible host. Choices B, C, and D are incorrect because they do not follow the correct sequence of events in the cycle of infection.

5. Which verb tense best fits the blank: 'By next month, she _____ the project for a year.'

• A. will have been working on
• B. will work on
• C. has been working on
• D. had worked on

Correct answer: A

Rationale: The correct answer is 'A: will have been working on.' In this sentence, the future perfect continuous tense is needed to convey that the action of working on the project will continue up to a specific future point (next month). Choices B, C, and D are incorrect. Choice B ('will work on') indicates a future action without emphasizing the duration of the action. Choice C ('has been working on') is in the present perfect continuous tense, which does not convey the future duration of the action. Choice D ('had worked on') is in the past perfect tense, which is not suitable for indicating an action continuing up to a future point.
