2. They_m__o_v_e_d_(move) to the south in 1990 and _h_a_v_e__li_v_e_d_(live)there since then.
(tour) The present perfect continuous tense can’t be used with time expressions such as twice or how many times, because in this tense the action is continuous, not stopped and started again. We can use the present perfect tense for repeated actions, and the present perfect continuous tense for non-stop actions.
Note:
We use the present perfect tense to talk about actions that were completed only a short time ago. In this case, just is used. Pay attention to the position of just.
