Hi Brian,
Unfortunately, some answers that are very easy for native speakers are not that easy for non native speakers. Especially phrasal verbs , which are ,to some extend ,idomatic phrases, so if I haven't heard a particular phrasal verb used in a certain context and my dictionary doesn't have the meaning I'm looking for than i have no idea which ph.v. is correct.
When it comes to my examples I would put 'take up' in #2, but it's a pure gues, so I'm not sure if it's ok, in #1 I have no idea what ph.v. fits the sentence

p.s.
I have only handouts with exercises, no list of ph.v. , no course book.
