Answer 1

Verified answer

1. Some people are worried that the computer will gradually (b. replace) human labor.

Karena maksud dari kalimat ini adalah bahwa computer akan menggantikan human labor. "Menggantikan" dalam bahasa inggris adalah replace.

2. The sound (a. comes) from a vibrating object will be high or low depending on the number of vibrations.

Karena kalimat ini bermaksud menjelaskan suatu kebenaran yang bersifat umum, universal (general truth), sehingga harus menggunakan present simple tense, di mana Verb yang digunakan adalah bentuk pertama.

3. When will you do your homework? it is twelve o'clock now and you (b. have been reading) magazine since five.

Karena kalimat ini menegaskan bahwa si pelaku sudah sejak beberapa waktu yang lalu masih membaca majalah hingga saat pembicara tersebut menegurnya. Sehingga digunakan present perfect continuous tense, di mana rumusnya have/has been + V1+ing

Semoga dapat dipahami :)
