Answer 2

a.He has been waiting ...before they arrived ( se foloseste has been waiting - present perfect continuous, pentru ca vorbim despre un interval de timp for half an hour - timp de o jumatate de ora - este regula lui since si for)
b.  was he going... when you saw him (se foloseste past tense continuous- pentru ca tradurerea este a unui verb continuu - unde mergea el - adica era in miscare, si intotdeauna can dverbul se traduce cu imperfect in limba romana, in engleza este past tense continuous)
c  He phoned me
d.    was talking to John.... when I walked in  (la fel se aplica regula si aici, alui past tense continuous - el vorbea cu john, cand eu am intrat)
