In the two cases below, do the verbs require -s endings i.e. do the verbs refer to it (the largest amount/the upper range) or to they (particles/ratios):
The upper range for risk ratios exceed(s?) unity.
The largest amount of particles accumulate(s?) on the surface.
Your help is appreciated!
range clearly requires exceeds.
It's more complicated with a "group" noun like "amount".
For the largest amount of particles, I'd write accumulate.
In fact, I'd write instead "Most of the particles accumulate on the surface."
"The majority of particles accumulate ..." In terms of particles, "the largest amount" is plural.
"The largest amount of particles accumulate on the surface."
I'm sure someone else would prefer accumulates though.
