Read the following sentence to answer the question below: He is a kind and generous man who wants nothing more than the best for his community, thought Michael as the board members discussed the nominees for head of council. Lana June, however, was far more critical. He is just saying those things to get elected, she thought.
What is the author's point of view?
- A. First person
- B. Third person limited
- C. Third person omniscient
- D. Objective
Correct Answer: B
Rationale: The passage is told from a third person limited point of view because the thoughts and perspectives of two specific characters, Michael and Lana June, are presented. The narrator provides insight into their thoughts, but remains limited to their viewpoints without revealing the thoughts of any other characters. This extract demonstrates the limited perspective by showing the inner thoughts of Michael and Lana June, indicating a third person limited narrative. Third person omniscient would involve knowing the thoughts of all characters, which is not the case here. First person would involve using 'I' to narrate, which is absent. Objective point of view would present only observable actions without any character's thoughts or feelings, which is not the case in this 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.
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.
Scientist: Last year was the warmest ever recorded in the last 134 years.
During that time period, the ten warmest years have all occurred since 2000.
This correlates directly with the recent increases in carbon dioxide as large
countries like China, India, and Brazil continue developing and
industrializing. No longer do just a handful of countries burn massive amounts
of carbon-based fossil fuels; it is quickly becoming the case throughout the
whole world as technology and industry spread.
Politician: Yes, but there is no causal link between increases in carbon
emissions and increasing temperatures. The link is tenuous and nothing close
to certain. We need to wait for all of the data before drawing hasty conclusions. For all we know, the temperature increase could be entirely
natural. I believe the temperatures also rose dramatically during the dinosaurs'
time, and I do not think they were burning any fossil fuels back then.
How does the author generally present the information in the extract?
- A. Chronological order
- B. Comparison-contrast
- C. Cause-effect
- D. Conclusion-premises
Correct Answer: C
Rationale: The author generally presents the information in a cause-effect format. The scientist talks about the increase in carbon dioxide emissions by countries like China, India, and Brazil leading to rising global temperatures. The politician, on the other hand, argues against a causal link between carbon emissions and temperature increase, suggesting a natural rise in temperatures. The information is structured around the cause of carbon emissions and its effect on global temperatures. Choice A, chronological order, is incorrect as the information is not presented in a time sequence but rather based on cause and effect. Choice B, comparison-contrast, is not the best description as the focus is more on cause and effect rather than comparing or contrasting different elements. Choice D, conclusion-premises, is also incorrect as the information does not follow the pattern of drawing conclusions based on premises but rather discusses the relationship between carbon emissions and temperature increase.

In which chapter should she look for more information on herbal remedies to combat eczema?
- A. Chapter 8
- B. Chapter 10
- C. Chapter 11
- D. Chapter 12
Correct Answer: D
Rationale: Eczema is a topical condition, so Chapter 12 (section D) would be the most appropriate place to look for information on herbal remedies to combat it. Chapter 8 focuses on herbs for adult needs, and while it may contain some relevant information, it is not specific to topical conditions like eczema. Chapters 10 and 11 cover respiratory and digestive conditions respectively, which are not relevant to treating eczema. Therefore, Chapter 12 is the best choice for Clothilde to find herbal remedies to combat eczema.
NOTE: The instructor of a history class has just finished grading the essay exams from his students, and the results are not good. The essay exam was worth 70% of the final course score. The highest score in the class was a low B, and more than half of the class of 65 students failed the exam. In view of this, the instructor reconsiders his grading plan for the semester and sends out an email message to all students.
What is the best summary of the instructor's motive in sending the email to the students?
- A. Expressing concern about students' grades and emphasizing the importance of being worried.
- B. Recognizing the low exam scores and the need to adjust the grading plan to help students improve.
- C. Explaining the purpose of a group project and how it benefits students working together.
- D. Stating the strict grading policy set at the beginning of the semester.
Correct Answer: B
Rationale: Answer choice B is the correct summary of the instructor's motive in sending the email to the students. The passage mentions that the instructor acknowledged the low exam scores, including a high failure rate and the need to reconsider the grading plan for the semester. This indicates that the instructor wants to adjust the grading plan to provide students with an opportunity to improve their scores. Choice A is incorrect as it focuses on expressing concern rather than on adjusting the grading plan. Choice C is unrelated as it discusses the purpose of a group project. Choice D is also incorrect as it mentions the strict grading policy set at the beginning of the semester, which is not the main focus of the email sent by the instructor.
