You have to allow xing2 hang2 to both be right for 行, le5 liao3 to both be accepted for 了, etc. There is NO way to tell them apart, and it's simply a matter of luck (not skill, we are developing a skill here, right???) as to whether you get it "right". Of course, these options are all right, given just a character and no context or example sentence.
This needs to be fixed.
xing2 is a noun and a verb
hang2 is only a verb
you can pick the right one by seeing which part of speech it is asking for.
however, there are other examples where you can't tell them apart 觉 jue2 and 觉 jiao4. same character, both verbs, diff't meanings.
Posted by Big_Kahuna 8/19/12 (9 months ago)The Brazilian Portuguese conjunctions course has this problem too - there are two phrases that mean 'so that', and it's impossible to tell which one the question wants. Very frustrating, especially given it's a hard course already :(
