Please, correct me if I am wrong:
participal phrase at the end of the sentence or inbetween can modify
a) the word after which it stands
b) the subject
c) phrase??? or part of the clause after which it stands
d) the whole preceeding clause
My examples:
a) Our car was repaired by a mechanic, working as quickly as possible. (the second part modifies mechanic)
b) Maria went to sleep, hoping to please her mother. (hoping modifies Maria)
Maria went to sleep, awakening to scary dreams, relieved when it was morning (awakening modifies Maria)
c) Among lower- paid workers, union members are less likely than non union members to be enrolled in lower- end insurance plans that impose stricter limits on medical services and require doctors to see more patients, spending less time with each. ("spending less with each" modifies "require doctors to see more patients")
d) The cameras of the Voyager II spacecraft detected six small, previously unseen moons circling Uranus, doubling to twelve the number of satellites now known as orbiting. (the second part modifies the first part).
Please, provide your examples. In my opinion it is a common trap which is used by GMAC when you solve hard questions.
