Answer:
Cause-and-effect relationships are signaled by the words "he finally convinced," "which 'met an unperceived need,'" and "Early results."
Explanation:
In the excerpt taken from "The Evolution of Useful Things," we can describe the relationship of ideas in the following manner:
B. The passage of time is signaled by the words "he finally convinced," "Early results," and "customers became."
- In the excerpt we are analyzing here, there is a clear relationship between the ideas to show the passage of time.
- Words such as "finally" and "early" are used to do precisely that - show the sequence of events over time.
- In the passage, we are told how, after some time, Fry was (finally) able to convince the office-supply division to test his product.
- At first, the (early) results were not promising. But, after distributing samples, the customers became hooked.
- There is clearly a passage of time between the three events: convincing the division, obtaining results, and then getting customers interested.
- With that in mind, we can choose letter B as the best option.
This is the complete passage:
Fry was committed to his brainchild, however, and he finally convinced an office-supply division of 3M to test-market the product, which "met an unperceived need." Early results were not at all promising, but in those cases where samples were distributed, customers became hooked.
