Nokea
The mother sun-fish, having now built or provided her "hatchery,"
deposits her spawn within the circular inclosure, and mounts guard at the
entrance until the fry are hatched out and are sufficiently large to take
charge of themselves.
What does the word 'wise' in this passage most closely mean?
- A. Manner
- B. Knowledge
- C. Shrewd
- D. Ignorance
Correct Answer: A
Rationale: In the context of the passage, the word 'wise' refers to the 'manner' in which the sun-fish builds its hatchery. It describes the careful and skillful way in which the mother sun-fish constructs and provides for her offspring. Choice B, 'Knowledge,' is incorrect as the word 'wise' does not specifically imply knowledge in this passage. Choice C, 'Shrewd,' is incorrect as it suggests cleverness or astuteness, which is not the intended meaning here. Choice D, 'Ignorance,' is the opposite of 'wise' and does not align with the context of the passage.

This excerpt is adaptation from The Life-Story of Insects, by Geo H. Carpenter.
Insects as a whole are preeminently creatures of the land and the air. This is shown not only by the possession of wings by a vast majority of the class, but by the mode of breathing to which reference has already been made, a system of branching air-tubes carrying atmospheric air with its combustion-supporting oxygen to all the insect's tissues. The air gains access to these tubes through a number of paired air-holes or spiracles, arranged segmentally in series.
It is of great interest to find that, nevertheless, a number of insects spend much of their time under water. This is true of not a few in the perfect winged state, as for example aquatic beetles and water- bugs ('boatmen' and 'scorpions') which have some way of protecting their spiracles when submerged, and, possessing usually the power of flight, can pass on occasion from pond or stream to upper air. But it is advisable in connection with our present subject to dwell especially on some insects that remain continually under water till they are ready to undergo their final moult and attain the
winged state, which they pass entirely in the air. The preparatory instars of such insects are aquatic; the adult instar is aerial. All may-flies, dragon-flies, and caddis-flies, many beetles and two- winged flies, and a few moths thus divide their life-story between the water and the air. For the present we confine attention to the Stone-flies, the May-flies, and the Dragon-flies, three well-known orders of insects respectively called by systematists the Plecoptera, the Ephemeroptera and the Odonata.
In the case of many insects that have aquatic larvae, the latter are provided with some arrangement for enabling them to reach atmospheric air through the surface-film of the water. But the larva of a stone-fly, a dragon-fly, or a may-fly is adapted more completely than these for aquatic life; it can, by means of gills of some kind, breathe the air dissolved in water.
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: The definition that most closely relates to the usage of the word 'moult' in the passage is the act of shedding part or all of the outer shell. The passage mentions how some insects remain under water until they are ready to undergo their final moult and attain the winged state. This process involves shedding their old skin or exoskeleton to transition from the aquatic larval stage to the aerial adult stage. Choices A, B, and D are incorrect because they do not align with the specific context provided in the passage. Choice A talks about an adventure underwater, which is unrelated to the biological process of moulting. Choice B refers to a mating act between insects, which is not the focus of the passage. Choice D discusses the death of an organism leading to a revival of life, which is not connected to the moulting process described in the passage.
Smoking tobacco products is terribly destructive. A single cigarette contains
over 4,000 chemicals, including 43 known carcinogens and 400 deadly toxins.
Some of the most dangerous ingredients include tar, carbon monoxide,
formaldehyde, ammonia, arsenic, and DDT. Smoking can cause numerous
types of cancer including throat, mouth, nasal cavity, esophagus, stomach,
pancreas, kidney, bladder, and cervical.
Cigarettes contain a drug called nicotine, one of the most addictive substances
known to man. Addiction is defined as a compulsion to seek the substance
despite negative consequences. According to the National Institute of Drug
Abuse, nearly 35 million smokers expressed a desire to quit smoking in 2015;
however, more than 85 percent of those addicts will not achieve their goal.
Almost all smokers regret picking up that first cigarette. You would be wise to
learn from their mistake if you have not yet started smoking.
According to the U.S. Department of Health and Human Services, 16 million
people in the United States presently suffer from a smoking-related condition
and nearly nine million suffer from a serious smoking-related illness.
According to the Centers for Disease Control and Prevention (CDC), tobacco
products cause nearly six million deaths per year. This number is projected to
rise to over eight million deaths by 2030. Smokers, on average, die ten years
earlier than their nonsmoking peers.
In the United States, local, state, and federal governments typically tax
tobacco products, which leads to high prices. Nicotine addicts sometimes pay
more for a pack of cigarettes than for a few gallons of gas. Additionally,
smokers tend to stink. The smell of smoke is all-consuming and creates a
pervasive nastiness. Smokers also risk staining their teeth and fingers with
yellow residue from the tar.
Which of the following statements most accurately summarizes the passage?
- A. Tobacco is less healthy than many alternatives.
- B. Tobacco is deadly, expensive, and socially unappealing.
- C. The US typically taxes tobacco products, leading to high prices.
- D. Tobacco products shorten smokers' lives by ten years and kill millions.
Correct Answer: B
Rationale: The correct answer is B. The passage extensively details the destructive nature of smoking tobacco products, highlighting the numerous harmful chemicals, addictive properties of nicotine, increased risk of various cancers, serious health conditions, and premature deaths associated with smoking. It also mentions the high costs due to government taxation on tobacco products, alongside the negative social aspects like the smell and staining effects. Choice A is incorrect as the passage emphasizes the severe dangers rather than comparing the healthiness of tobacco to other alternatives. Choice C is incorrect as it focuses solely on the financial aspect of tobacco taxation, omitting the broader health and social consequences discussed in the passage. Choice D is partially correct but not as comprehensive as choice B, which encapsulates the deadly, expensive, and socially unappealing nature of tobacco use as portrayed in the passage.
A food chain is a diagram used by biologists to better understand ecosystems.
It represents the interrelationships between different plants and animals. The
energy is derived from the sun and converted into stored energy by plants
through photosynthesis, which travels up the food chain. The energy returns
to the ecosystem after the organisms die and decompose back into the Earth.
This process is an endless cycle.
In food chains, living organisms are grouped into categories called primary
producers and consumers, which come in multiple tiers. For example,
secondary consumers feed on primary consumers, while tertiary consumers
feed on secondary consumers. Apex predators are the animals at the top of the
food chain. They are the highest category consumer in an ecosystem, and apex
predators do not have natural predators.
What would a mongoose likely eat according to the food chain diagram?
- A. Shrub
- B. Aardvark
- C. Vulture
- D. Mouse
Correct Answer: D
Rationale: According to the food chain diagram, mongooses are consumers that feed on smaller animals like mice, making choice D the correct answer. Shrub (choice A) is a plant and not a typical food for mongooses. Aardvark (choice B) is a large mammal that is not a primary food source for mongooses. Vulture (choice C) is a scavenger bird that typically feeds on carrion, not a preferred food for mongooses.
Volleyball is easy to learn and fun to play in a physical education class. With just one net and one ball, an entire class can participate. The object of the game is to get the ball over the net and onto the ground on the other side. At the same time, all players hours be in the nready position to keep the ball from hitting the ground on their own side. After the ball has been served, the opposing team may have three hits to et the ball over the net to the other side. Only the serving team may. score. If the receiving team wins the volley, the referee calls, "side out" and the receiving team wins the serve. Players should rotate positions so that everyone gets a chance to serve. A game is played to 15 points, but the winning team must win by two points. That means if the score is 14 to 15, the play continues until one team wins by two. A volleyball match consists of three games. The winner of the match is the team that wins two of the three games.
How many people can participate in a volleyball game?
- A. 14
- B. 15
- C. half of a class
- D. an entire class
Correct Answer: D
Rationale: Based on the extract provided, a volleyball game can involve an entire class participating. The passage mentions that with just one net and one ball, an entire class can play volleyball. While the number of participants in a volleyball game can vary, the specific reference to a whole class in the passage indicates that a significant number of people can take part. Therefore, the correct answer is 'an entire class.'
Choice A, '14,' is incorrect because the passage explicitly mentions that an entire class can participate, which typically involves more than 14 individuals. Choice B, '15,' is incorrect as it does not account for the flexibility of the number of participants in a volleyball game as stated in the passage. Choice C, 'half of a class,' is incorrect as the passage clearly states that an entire class can participate, not just half.
The Dewey Decimal System is a library classification system: 000 Computer science, 100 Philosophy and psychology, 200 Religion, 300 Social sciences, 400 Languages, 500 Science, 600 Technical science, 700 Arts, 800 Literature, 900 History.
While researching Chomsky's many theories and arguments, Teddy became interested in post-World War II anarchism. Which section of the library is the most likely to contain the relevant books?
- A. 000
- B. 200
- C. 300
- D. 900
Correct Answer: C
Rationale: Since anarchism is a social science theory, it falls under the classification of social sciences in the Dewey Decimal System. Section 300 covers social sciences, making it the most suitable section for finding books related to post-World War II anarchism. Choice A (000 - Computer science), Choice B (200 - Religion), and Choice D (900 - History) are incorrect because they do not directly relate to social sciences where anarchism would be classified.
