I have some location problems with sentences that have more than one prepositional phrase or conjunction. Examples,
- I decided to come there yesterday.
What does it mean? I decided it yesterday or I came there yesterday.
- I have been working in order to have good life conditions since I graduated.
Is this correct? I think that "since I graduated" is too far away from "working", because "in order to.." separates them from each other. It seems confusing, what do you suggest? Thanks.
