Read the events that led to Art Fry's creation of temporarily permanent bookmarks described in The Evolution of Useful Things.

Fry spent nearly a year and a half experimenting.

Fry's idea was accepted as being commercially viable.

Spencer Silver came upon a curious adhesive that he demonstrated to Fry.

Fry reflected on the failure of bookmarks to do all that might be expected of them.

Which is the correct order of the events?

1, 2, 3, 4

2, 4, 3, 1

3, 4, 1, 2

4, 2, 1, 3

Hi! The correct order of the events that led to Art Fry's creation of temporarily permanent bookmarks described in The Evolution of Useful Things is: 3,4,1,2. The correct answer is the third one.

Explanation:

I chose the third option (3,4,1,2) because, according to the text, the chronological order for the things that led Art Fry's creation are:

Spencer Silver came upon a curious adhesive that he demonstrated to Fry. Fry reflected on the failure of bookmarks to do all that might be expected of them. Fry spent nearly a year and a half experimenting. Fry's idea was accepted as being commercially viable.

Besides the way in which these events were described by the author, and if you think about it, it is pretty logical the way this happened. Usually, we come up with ideas when we are complaining about the lack of a thing that would be useful in certain moments. If you think about it, this is also what happened here. The last step of the process is always the commercial viability just as in this case.
