IMO A is not correct for 9th. there is no proof for that.also, it cannot be assumed .
B is somewhat implied
here is my explanation. discussions are welcome
Q7B
read the first 15 lines. They establish a relationship between innovation and patents.
an example is discussed in the following lines.
A says passage is concerned with the exmple. incorrect
B there is no advocation here at all, only the problem is presented.incorrect
C correct
D & E out of scope.
Q8D
self explanatory, if someone has a question feel free to ask.
Q9B
for those saying A, my question is this..how do you quantify "early 1980s"?
in other words tell me the years in question. u can't. it is generally believed
"early" would refer to the first few years of the decade(1-5 yrs). in the middle of the early
period(i.e 1982) you see a drop in the standard. also a decade later there might have been a raise.
so there is no justification for this.
B is implied. between 1982 and 1992 we see more patents but less quality.
C,D and E are irrelavant.
Q10E
Author's claim:quality can be measured using number of citations.
how to undermine: low quality getting many citations.
obviouslyE.
