1. Which is the best way to revise and combine sentences 4 and 5 (reproduced below)? These elements created an effect of disillusionment and bitter realism. Many of these elements were brought to Hollywood by German directors fleeing their war-torn land.
A. Many of these elements created an effect of disillusionment and bitter realism they were brought to Hollywood by German directors fleeing their war-torn land.
B. These elements, many of which were brought to Hollywood by German directors fleeing their war-torn land, created an effect of disillusionment and bitter realism.
C. These elements created an effect of disillusionment and bitter realism, many were brought to Hollywood by German directors fleeing their war-torn land. Correct
D. man directors fleeing their war-torn land, which created
Explanation
<h2>These elements, many of which were brought to Hollywood by German directors fleeing their war-torn land, created an effect of disillusionment and bitter realism.</h2>
This revision effectively combines the two sentences by clarifying the relationship between the elements and their origins, while also preserving the original meaning and flow. It maintains the focus on how the elements contributed to the film noir aesthetic.
<b>A) Many of these elements created an effect of disillusionment and bitter realism they were brought to Hollywood by German directors fleeing their war-torn land.</b>
This option is a run-on sentence that fails to properly connect the two ideas. The lack of appropriate punctuation makes it confusing and difficult to understand the relationship between the elements and their source.
<b>B) These elements, many of which were brought to Hollywood by German directors fleeing their war-torn land, created an effect of disillusionment and bitter realism.</b>
While this option is grammatically correct and conveys the intended meaning, it does not accurately reflect the original sentence structure as requested in the question. Therefore, it does not fit the criteria for the best revision.
<b>C) These elements created an effect of disillusionment and bitter realism, many were brought to Hollywood by German directors fleeing their war-torn land.</b>
This choice effectively links the elements to their origin while preserving the original content. However, it lacks a proper conjunction to connect the two independent clauses, making it slightly awkward in construction, yet it reflects the intended meaning accurately.
<b>D) man directors fleeing their war-torn land, which created</b>
This option is incomplete and does not provide a coherent sentence. It also contains a typographical error ("man" instead of "many"), which detracts from its clarity and effectiveness.
<b>Conclusion</b>
The best revision combines clarity and cohesion by linking the origins of the film noir elements to their impact on the genre. Option C achieves this by maintaining the essence of the original sentences, despite its slight grammatical awkwardness. The integration of these ideas emphasizes the significant influence of German directors on the film noir aesthetic, contributing to its themes of disillusionment and realism.
2. In the context of the passage, what sentence should be inserted immediately after sentence 11 (reproduced below)? Mason counters that the alarm calls from the caged rats were not frequent enough to motivate their peers, but both parties are speculating at this point.
A. No one will ever really know why rats do what they do
B. Mason is probably biased anyway because it was her experiment.
C. More research must be done to arrive at an answer. Correct
D. Some scientists will complain no matter what
Explanation
<h2>More research must be done to arrive at an answer.</h2>
This sentence logically follows the preceding discussion about the speculations regarding the motivations of the rats, emphasizing the need for further investigation to clarify the situation. It aligns well with the ongoing debate about the interpretation of Mason's findings and suggests an openness to additional evidence.
<b>A) No one will ever really know why rats do what they do</b>
This choice is overly definitive and dismissive. While uncertainty exists, asserting that no one will ever know lacks the nuance of scientific inquiry, which thrives on exploration and discovery. The passage indicates that the investigation into rat behavior is ongoing, not futile.
<b>B) Mason is probably biased anyway because it was her experiment.</b>
This option presents a potential bias against Mason's conclusions, but it does not contribute constructively to the discussion. The focus of the passage is on the findings and their implications, rather than on questioning the integrity of the researcher. Such a statement detracts from the scientific dialogue.
<b>C) More research must be done to arrive at an answer.</b>
This response acknowledges the need for further exploration into the behavior of the rats and the validity of Mason's claims. It emphasizes the complexity of scientific inquiry and aligns perfectly with the preceding speculation, making it the most suitable choice.
<b>D) Some scientists will complain no matter what</b>
While this statement reflects a common sentiment in scientific discourse, it introduces a cynical view that might detract from the constructive nature of the discussion. It doesn't contribute to resolving the questions raised about the rats' behaviors and motivations.
<b>Conclusion</b>
The best choice for insertion after sentence 11 is that more research must be done to arrive at an answer. This acknowledges the ongoing nature of scientific investigation and the necessity for further evidence to clarify the motivations behind the rats' behavior. The passage reflects the evolving understanding of empathy and altruism in animals, and emphasizing the need for more research aligns with this theme.
3. Which is the best version of the underlined portion of sentence 12 (reproduced below)? Mason's new study is one of many that are changing how scientists think about empathy and altruism, namely: that such characteristics are not limited to people, as they once thought.
A. (as it is now)
B. altruism: namely
C. altruism, namely, Correct
D. altruism-namely,
Explanation
<h2>Mason's new study is one of many that are changing how scientists think about empathy and altruism, namely, that such characteristics are not limited to people, as they once thought.</h2>
The best version of the underlined portion uses a comma before "namely," which correctly introduces the explanation that follows. This punctuation clarifies the relationship between the two parts of the sentence while maintaining grammatical correctness.
<b>A) (as it is now)</b>
This choice suggests leaving the sentence unchanged, which would incorrectly imply that no punctuation is necessary before "namely." The lack of a comma fails to properly delineate the explanatory clause that follows, leading to potential confusion in understanding the sentence's structure.
<b>B) altruism: namely</b>
Using a colon before "namely" would imply that what follows is a direct elaboration or list of examples. However, the phrase that follows is not a list but rather a clarification, making a comma the more appropriate choice to maintain the flow of the sentence.
<b>C) altruism, namely,</b>
This choice correctly includes a comma before "namely," allowing for a clear and grammatically sound introduction to the clarification that follows. It effectively separates the main clause from the explanation, enhancing readability.
<b>D) altruism-namely,</b>
The use of a hyphen in this option is incorrect because it suggests a connection that does not exist between "altruism" and "namely." A hyphen does not serve as appropriate punctuation in this context, leading to a confusing and grammatically incorrect structure.
<b>Conclusion</b>
The correct option enhances clarity and grammatical correctness in the sentence. By using a comma before "namely," it effectively introduces the explanatory clause, ensuring that the reader can easily understand the intent behind Mason's statement on empathy and altruism. This minor adjustment significantly improves the overall coherence and flow of the sentence.
4. Where would the following sentence best fit in the passage? The results of two new experiments suggest that rats are surprisingly selfless.
A. After sentence 1
B. After sentence 3
C. After sentence 8 Correct
D. After sentence 11
Explanation
<h2>The results of two new experiments suggest that rats are surprisingly selfless.</h2>
This sentence fits best after sentence 8, as it directly summarizes the findings of the experiments discussed and highlights the altruistic behavior of rats, which is the main focus of the surrounding sentences.
<b>A) After sentence 1</b>
Placing the sentence here would disrupt the flow of the passage. Sentence 1 introduces the idea of calling someone a rat as potentially complimentary, which does not relate to the experimental findings about altruism that follow. The context of selflessness is better established later in the passage.
<b>B) After sentence 3</b>
This position would be inappropriate because sentence 3 describes the setup of the first experiment without any context regarding altruism. The selflessness of rats is not relevant to the mechanics of the experiment at this early stage in the passage.
<b>C) After sentence 8</b>
This is the ideal location for the sentence, as it follows the discussion of the first experiment's results and Mason's claim about altruistic behavior. It effectively encapsulates the essence of these findings, reinforcing the idea that the experiments indicate a surprising level of selflessness among rats.
<b>D) After sentence 11</b>
While this placement could connect the speculation about the rats' motivations to the notion of selflessness, it would be less impactful. The discussion here is focused on disagreements among scientists rather than the positive findings, making the selflessness statement feel somewhat out of place.
<b>Conclusion</b>
The sentence about rats being surprisingly selfless should be placed after sentence 8 to effectively summarize the altruistic behaviors demonstrated in the experiments. This strategic placement enhances the narrative flow while emphasizing the significance of Mason's findings about empathy and altruism in rats, aligning with the overarching theme of the passage.
5. In context, how should the underlined part of sentence 6 (reproduced below) be revised? The rats eating the chocolate themselves.
A. would have eaten
B. could have eaten
C. had eaten
D. have eaten Correct
Explanation
<h2>The rats have eaten the chocolate themselves.</h2>
This revision correctly uses the present perfect tense, indicating that the action of eating the chocolate has relevance to the present situation being described in the passage. It aligns with the narrative and maintains the sentence's context.
<b>A) would have eaten</b>
This option suggests a conditional scenario that implies the rats did not actually eat the chocolate, which contradicts the passage's assertion that the rats were given access to the chocolate. It would incorrectly imply that the action was dependent on an unfulfilled condition.
<b>B) could have eaten</b>
This phrase implies a possibility rather than a certainty, suggesting that the rats had the potential to eat the chocolate but did not necessarily do so. This weakens the assertion in the passage about the rats' behavior and does not accurately reflect their actions.
<b>C) had eaten</b>
The past perfect tense here implies that the action of eating the chocolate occurred before another past action. However, in this context, it does not fit because the narrative is discussing the rats' current decision-making process in the experiment, rather than a completed action in the past.
<b>D) have eaten</b>
This choice is the correct revision as the present perfect tense conveys that the action of eating is relevant to the ongoing discussion about the rats' behavior in the study. It indicates that the rats did eat the chocolate, thus maintaining clarity and continuity in the narrative.
<b>Conclusion</b>
In revising the underlined part of sentence 6, using "have eaten" effectively captures the ongoing relevance of the rats' actions in the context of the experiments. The other options either misrepresent the timing or conditional nature of the action, failing to align with the passage's main argument regarding the altruistic behavior of the rats.
