1. Why do cicadas make a buzzing sound?

• A. To orient via echolocation
• B. To attract a mate
• C. To locate a food source
• D. To ward off predators

Correct answer: B

Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.

2. What would this author's attitude likely be towards a person unable to find employment?

• A. Descriptive
• B. Conciliatory
• C. Ingenuous
• D. Incredulous

Correct answer: D

Rationale: The author's likely attitude towards a person unable to find employment would be incredulous. The passage emphasizes the abundance of job opportunities in the United States and suggests that finding employment should not be difficult for those willing to work. The author believes that with the numerous avenues of success and available vocations, anyone who is willing to engage in a respectable occupation should be able to find lucrative employment. Therefore, the author would find it hard to believe or be skeptical towards someone who claims they cannot find a job. Choice A, 'Descriptive,' is incorrect as the author's attitude is more judgmental than just describing a situation. Choice B, 'Conciliatory,' is incorrect as the author does not show any intention to reconcile or make peace with the situation of unemployment. Choice C, 'Ingenuous,' is incorrect as this term means innocent or naive, which does not align with the author's likely attitude of disbelief towards unemployment.

3. Which definition most closely relates to the usage of the word 'moult' in the passage?

• A. An adventure of sorts, especially underwater
• B. Mating act between two insects
• C. The act of shedding part or all of the outer shell
• D. Death of an organism that ends in a revival of life

Correct answer: C

Rationale: 'Moult' refers to the act of shedding the outer shell, which is part of the insect's development. In the passage, it mentions insects that remain continually under water until they are ready to undergo their final moult and attain the winged state. This process of shedding the outer shell is crucial for insects transitioning from their aquatic larval stage to their aerial adult stage. Choices A, B, and D do not align with the specific context provided in the passage about the term 'moult.'

4. Which of the following would weaken the author's argument?

• A. a report revealing that the cited study was funded by a company that provides discounted tutoring through schools
• B. a study demonstrating differences in standardized test scores among students at schools in various neighborhoods
• C. a statement signed by local teachers affirming that they do not give preferential treatment in the classroom or during grading
• D. a study indicating that GPA has a weak correlation with success in college

Correct answer: A

Rationale: Choice A weakens the author's argument by highlighting a potential conflict of interest. If the cited study was funded by a company offering discounted tutoring, it could introduce bias and question the credibility of the study's findings. This revelation could cast doubt on the objectivity and reliability of the research, ultimately undermining the argument based on the cited study. Choices B, C, and D do not directly impact the credibility or objectivity of the cited study, so they would not significantly weaken the author's argument.

5. How did Hedy Lamarr contribute significantly to the advancement of technology?

• A. The technology of the era wasn't advanced enough to easily implement Lamarr's system
• B. She collaborated with the science engineering team employed by Howard Hughes, the aviation tycoon
• C. She had several failed inventions, such as an improved traffic light and a carbonated drink
• D. Her work led to the future development of cellular phones, Bluetooth, and Wi-Fi.

Correct answer: D

Rationale: The correct answer is D because Hedy Lamarr's invention of a frequency-hopping system, along with George Antheil, laid the foundation for technologies like cellular phones, Bluetooth, and Wi-Fi. This significant contribution revolutionized communication technology. Choice A is incorrect because it focuses on the limitations of the era's technology rather than Lamarr's contributions. Choice B is incorrect as it briefly mentions her collaboration but does not directly relate it to technological advancements. Choice C is incorrect as it highlights her failed inventions, which are not indicative of her significant contributions to technology.
