I got 2 incorrect.
Here is how I feel this is passage is structured
Studies of the effect of viewers' involvement in television programs on their responses to commercials have produced varied conclusions.
Conclusion 1: Some researchers argue that a high level of program involvement inhibits viewer processing of commercial messages
Experiment 1: Advertisement recall was highest for the non-engaging shows and least for the most engaging shows
Conclusion 2: the persuasive impact of commercials increases as interest in the program increases.
Experiment 2: less positive when commercials appeared during programs with "natural breaks” than when they appeared in an “interrupted context”
Lords conclusion 3: certain program content induces viewers to commit a large proportion of their attention to its processing, minimizing the efficiency with which they can process information conveyed by a commercial.
1. Which of the following best describes the function of the sentence highlighted in the context of the passage as a whole?
(Finally, Lord concluded that certain program content induces viewers to commit a large proportion of their attention to its processing, minimizing the efficiency with which they can process information conveyed by a commercial.)
A) It offers a generalization about certain types of studies discussed in the passage. (It is not a generalization but a conclusion or interpretation in itself)
B) It presents evidence that supports an assertion made in the preceding sentence. (Doesn't provide any evidence)
C) It summarizes the prevailing interpretation of experimental results described earlier in the passage. (We don't know if the interpretation is prevailing also summarizes is incorrect)
D) It introduces a theory that reconciles the views of two researchers mentioned earlier in the passage. (Doesn't seem to be a theory + author doesn't say anything about it reconciles the other theories)
E) It provides a possible explanation for certain observations described earlier in the passage. (Correct: Best option so far)
