Penjelasan:

- "while”digunakan untuk mendeskripsikan dua tindakan yang ditopang oleh dua objek berbeda dalam kerangka waktu yang sama. Artinya ada 2 aksi yang dilakukan pada waktu yang bersamaan, oleh karena itu keduanya menggunakan past continuous tense.

- Konjungsi “when” digunakan untuk menunjukkan hubungan antara dua tindakan yang keduanya terjadi dalam Simple Present Tense.

seperti contoh :

When the doorbell rang, the old man was having a nap in the living room.
