A new study published in the journal Science shows definitive evidence of organic matter on the surface of Mars. The data was collected by NASA's nuclear-powered rover Curiosity. It confirms earlier findings that Mars, the Red Planet once contained carbon-based compounds. These compounds – also called organic molecules – are essential ingredients for life as scientists understand it.

The organic molecules were found in Mars's Gale Crater, a large area that may have been a watery lake over three billion years ago. The rover encountered traces of the molecule in rocks extracted from the area. The rocks also contain sulfur, which scientists speculate helped preserve the organics even when the rocks were exposed to the harsh radiation on the surface of the planet.

Scientists are quick to state that the presence of these organic molecules is not sufficient evidence for ancient life on Mars, as the molecules could have been formed by non-living processes. But it's still one of the most astonishing discoveries, which could lead to future revelations. Especially when one considers the other startling find that Curiosity uncovered around five years ago.

Question: Why are the evidences in sufficient to claim life on Mars?

A. The molecules could have been formed by non-living processes.

B. The molecules exist everywhere on the planet.

C. All planets have these molecules.

D. The existence of these molecules is not strong enough.

Dịch: Các nhà khoa học nhanh chóng tuyên bố rằng sự có mặt của các phân tử hữu cơ không đủ bằng chứng để chứng minh có sự sống trước đây trên sao Hoả, vì các phân tử đó có thể được hình thành từ các quá trình không có sự sống.
