Speed Reading — Life on Mars - Level 0 — 200 wpm 

This is the text (if you need help).

Scientists have found deadly chemicals on Mars. They can kill any living thing. The chemicals mean the chance of finding life on Mars is very low. Mars has no ozone layer, so there is a lot of ultra-violet (UV) radiation. The UV rays and the chemicals make it impossible for anything to grow on Mars.

Just the chemicals are enough to kill living things. When they mix with UV rays, they kill living things 11 times faster. The scientists said their research shows that the land on Mars is deadly. They say the chemicals and UV rays mean that nothing can grow or live on the land or near the land on Mars.
