[japanjapan]

Dear teachers, i am busy these days, so these several days i have more questions. please forgive me and help me, thanks

far-reaching
implications, survey, question, reply,
among the four, which one is odd?
i chose implications, i don't think we can say far-reaching implications, am i right?
carve
a joint, a pencil, a statue, an initial
i chose an initial, i don't think we can carve "an initial" , am i right?

by the way, what's the difference of travel, trip and journey?
thanks a lot

"travel" is an umbrella term for trip and journey. "trip" refers to a long or short excursion, one that's usually quick and easy, whereas "journey" refers to a longer, slower period.
