Read the passage below and then choose the best answer to each question. Answer the questions on the basis of what is stated or implied in the passage.
Passage
Just downstream from its confluence with the Missouri River, near the town of Alton, Illinois, the Mississippi River is nearly one mile across. In contrast, there are sections of the river near its source (Lake Itasca in Minnesota), where the Mississippi spans less than 20 feet from its right bank to its left.
The passage is mainly discussing the Mississippi River's
- A. depth
- B. length
- C. width
- D. location
Correct Answer & Rationale
Correct Answer: C
The passage primarily focuses on the Mississippi River's width, detailing its varying measurements at different points along its course. This emphasis on width highlights its significance in navigation and ecology. Option A, depth, is not the main topic; while depth may be mentioned, it does not receive the same level of attention. Option B, length, is also a lesser focus, as the passage does not delve into the river's overall distance. Option D, location, is addressed but serves more as context rather than the central theme. Thus, width emerges as the key aspect discussed in the passage.

The retired government official spoke_______ about foreign policy and international trade.
- A. as knowing
- B. in knowledge
- C. knowledgeably
- D. knowledgeable
Correct Answer & Rationale
Correct Answer: C
Option C, "knowledgeably," is the appropriate choice as it is an adverb that describes how the retired government official spoke, indicating that he did so with knowledge and expertise. Option A, "as knowing," is grammatically incorrect in this context; it does not fit the structure of the sentence. Option B, "in knowledge," is awkward and does not function as an adverb, failing to appropriately modify the verb "spoke." Option D, "knowledgeable," is an adjective and does not correctly modify the verb, making it unsuitable for this sentence structure.

What assumption does the author of the passage make?
- A. Gases produced by algae will be cheaper to produce than other gases.
- B. The Department of Energy is already using hydrogen-producing algae as a source of energy
- C. Mutant versions of algae will not be capable of the process of photosynthesis
- D. Readers do not associate the Department of Energy with algae research.
Correct Answer & Rationale
Correct Answer: D
The assumption that readers do not associate the Department of Energy with algae research suggests a gap in public awareness that the author aims to address. This perspective is crucial for framing the significance of the research discussed. Option A is incorrect as it makes a specific economic claim not supported by the passage. Option B incorrectly assumes the Department of Energy is currently using hydrogen-producing algae, which is not established in the text. Option C presumes that mutant algae cannot photosynthesize, but the passage does not provide evidence or context to support this claim. Thus, D accurately reflects the author's underlying assumption about public perception.

The author uses a direct quotation (sentence 4) to
- A. present a skeptical opinion about Ardi
- B. provide eyewitness testimony about Ardi
- C. place Ardi in the context of other discoveries
- D. give a physical description of Ardi
Correct Answer & Rationale
Correct Answer: C
The use of a direct quotation in sentence 4 serves to place Ardi within the broader context of other significant discoveries, highlighting its relevance and importance in the field. This contextualization helps readers understand Ardi's significance in relation to other findings. Option A is incorrect; the quotation does not express skepticism but rather situates Ardi among other discoveries. Option B is also wrong, as the quotation does not provide firsthand eyewitness testimony. Lastly, option D is misleading; the quotation does not focus on a physical description of Ardi but emphasizes its contextual importance.

Beth was certain that tickets to the concert would sell quickly she ordered them online as soon the became available.
- A. quickly, she
- B. quickly, therefore
- C. quickly, so she
- D. quickly, then
Correct Answer & Rationale
Correct Answer: C
Option C, "quickly, so she," effectively connects Beth's belief about the tickets selling fast with her action of ordering them. The phrase "so she" indicates a cause-and-effect relationship, clarifying that her certainty motivated her decision. Option A, "quickly, she," lacks a clear connection between her belief and action, making the sentence feel incomplete. Option B, "quickly, therefore," is overly formal for this context and implies a logical conclusion rather than a direct action stemming from her belief. Option D, "quickly, then," suggests a sequence but does not imply causation, weakening the relationship between her certainty and her decision.
