Answer 2

1. Dịch : Mọi người đã rất cố gắng để tìm ra cách chữa trị cho căn bệnh này

-> Rất nhiều nỗ lực đã được thực hiện ( bởi mọi người) để tìm ra cách chữa trị cho căn bệnh này.

* try very hard = make every effort = make a lot of effort

-> thay vào :

People have tried very hard to find a cure for this disease.

-> People have made a lot of effort to find a cure for this disease . ( Câu này là vẫn đang chủ động )

-> Bị động : A lot of effort has been made to find a cure for this disease.

2.

* decide = made up one's mind : quyết định
