[1]Last October, a NASA rocket, traveling at a speed of 9,000 kilometers per hour, smashed into a deep, dark hole on the moon’s south pole.
Upon impact, the Centaur rocket kicked up a cloud of dust and elements from the moon’s surface, creating a so-called "ejecta-plume" that was monitored by NASA’s Lunar Reconnaissance Orbiter, or LRO.
Scientists analyzed the findings, and [2]prelimmary results from this mission suggested that there was some form of water on the moon. NASA lunar scientist Michael Wargo said those days that a wave of findings during the past year makes it certain.
"We’ve confirmed that there was indeed water ice in the ejecta-plume, and at an abundance that was about 50 percent greater than our initial estimates."
That means that the impact site has more water than some deserts on Earth.
1. According to the news report, what has happened last October?
2. What did preliminary results from this mission suggest?
选项

B、The water on the moon was as much as in the desert.
C、There was a lot of rocket remaining on the moon surface.
D、A large area has been affected by the rocket.
