The following passage is titled "Where Do Old Satellites Go When They Die?" by NASA. Like every other machine, satellites do not last forever. Whether their job is to observe weather, measure greenhouse gases in the atmosphere, or point away from Earth to study the stars, eventually all satellites grow old, wear out, and die, just like old washing machines and vacuum cleaners. So what happens when a trusty satellite's time has come? These days there are two choices, depending on how high the satellite is. For the closer satellites, engineers will use its last bit of fuel to slow it down. That way, it will fall out of orbit and burn up in the atmosphere. The second choice is to send the satellite even farther away from Earth. It can take a lot of fuel for a satellite to slow down enough to fall back into the atmosphere. That is especially true if a satellite is in a very high orbit. For many of these high satellites, it takes less fuel to blast it farther into space than to send it back to Earth.
The author supports the claim that satellites do not last forever through the use of which of the following?
- A. An anecdote about why satellites stop working when they do
- B. Examples of the ways satellites stop working over time
- C. A comparison of satellites to other common machines that stop working
- D. Suggestions for ways to keep satellites working over time
Correct Answer & Rationale
Correct Answer: C
The author effectively demonstrates that satellites do not last forever by comparing them to other common machines that also have limited lifespans. This comparison highlights the inevitability of wear and tear in technology, providing a relatable context for readers. Option A, an anecdote, may illustrate a specific instance but lacks the broader applicability needed to support the claim. Option B provides examples of satellite failures but does not frame them within a comparative context that strengthens the argument. Option D suggests preventive measures but does not address the inherent limitations of satellites, which is central to the claim.

Which of the following statements is true?
- A. Sentences 1 and 2 are compound sentences.
- B. Sentences 3 and 5 are complex sentences.
- C. Sentence 1 is complex and sentence 4 is simple.
- D. Sentence 2 is complex and sentence 6 is compound.
Correct Answer & Rationale
Correct Answer: A
Option A accurately identifies that sentences 1 and 2 are compound sentences, which consist of two independent clauses joined by a coordinating conjunction. This structure allows for the combination of related ideas, making the statement true. Option B incorrectly categorizes sentences 3 and 5 as complex. Complex sentences contain an independent clause and at least one dependent clause, which does not apply here. Option C misclassifies sentence 1 as complex; it is, in fact, compound. Additionally, sentence 4 is not simple, as it may contain additional clauses. Option D mistakenly labels sentence 2 as complex and sentence 6 as compound, which misrepresents their structures.

Which THREE of the following are considered to be features of an engaging oral presentation?
- A. Well paced rate of speech
- B. Consistent eye contact
- C. Use of multiple fillers (for example, "um," "like," "you know")
- D. Clear volume
- E. 5 to 15 minutes in length
Correct Answer & Rationale
Correct Answer: A, B, D
An engaging oral presentation includes a well-paced rate of speech (A), which helps maintain audience interest and ensures clarity. Consistent eye contact (B) fosters a connection with the audience, making the speaker appear more credible and engaging. Clear volume (D) ensures that the message is heard and understood, enhancing overall effectiveness. In contrast, the use of multiple fillers (C) detracts from the presentation's professionalism and can distract the audience. While a time limit (E) can be important, the specified length of 5 to 15 minutes is not universally applicable to all engaging presentations, as effectiveness varies based on context and content.

Which of the following words is most decodable?
- A. Always
- B. Stack
- C. Goes
- D. Write
Correct Answer & Rationale
Correct Answer: B
Decodable words are those that can be sounded out using phonetic rules. Option B, "Stack," is highly decodable as it follows straightforward phonetic patterns: each letter corresponds to a single sound, making it easy to pronounce. Option A, "Always," contains the vowel team "aw" and the silent "w," complicating its pronunciation. Option C, "Goes," includes an irregular vowel sound and a silent "e," which makes it less straightforward to decode. Option D, "Write," features a silent "w" and an irregular vowel sound, further reducing its decodability. Thus, "Stack" stands out as the most easily decodable option.

Which of the following parts of a textbook is most useful for locating a specific topic or idea quickly?
- A. Index
- B. Credits
- C. Prologue
- D. Table of contents
Correct Answer & Rationale
Correct Answer: A
The index is the most effective tool for quickly locating specific topics or ideas within a textbook. It provides a detailed alphabetical listing of subjects, complete with page numbers, allowing for efficient navigation. The credits section acknowledges contributors and sources but does not aid in finding content. The prologue introduces the book's themes and purpose, offering context rather than specific information. The table of contents outlines the main sections and chapters, but it lacks the granularity of the index, making it less effective for pinpointing particular topics.
