Penjelasan:

6. Can

karena kalau pakai would dia lebih sopan, dia seperti menanyakan kalau apakah boleh atau tidak dengan adanya probabilitas untuk menolak/ketersediaan individu. Kenapa gak could? Could itu utk sesuatu yang di masa lampau atau suatu probabilitas yang akan sulit terjadi.

When could is used as the past tense of can, it refers to an ability that a person generally had in the past or to something that was generally possible in the past. Could is also used to refer to something that you wish to have or do but that is not possible.

7. Could you give me your drink?

karena yang lain ga nyambung, arti yg pertama sama kedua dia minta obat, sedangkan dia itu haus. Kalo yg terakhir dia suruh temennya santai aja gitu, pdhl kan dia haus, apa hubungannya?
