ILL MARK BRAINLIST FRIST ANSWER Fry remembered a curious adhesive – a strong and yet easily removed “unglue”– that Spencer Silver . . . had come upon several years earlier. . . . Silver felt the unusual adhesive might have some commercial value. . . . At the time, no one had come up with a use for it, and so the formula for the weak adhesive was filed away – until the Monday morning when Fry came to work with the idea of making sticky bookmarks that could also be removed.

i have read the novel roll of thunder hear my cry by mildred d. taylor.

1. this isn't like any other story i've read or watched because it is about a black family in mississippi right after slavery in the u.s. had become illegal. most of the novels i have read were about slavery. another point is that the author of the novel used symbolism in a way i haven't seen before. for example she uses thunder as something negative meaning something bad will happen. but by the end of the novel, she made thunder a good thing.

2.   one character that changed during the novel was stacey. stacey is the eldest child of the black logan family. around the begging of the novel stacey was avoiding the white boy jeremy simms. he had a dislike for jeremy's family. but at the end of the novel stacey began to like jeremy.

3. the author starts the novel with the problem that the children of the logan family have to avoid the white kid school bus while walking to school.
