Here's your Shmoop du jour, brought to you by Vikings. In space. Wonder how they kept

Which of the following discoveries about Mars has been credited to the NASA missions?

00:50

By this point we've done a lot of skimming and rereading of the passage, so we're pretty

00:54

sure we can wing it, this time.

00:55

So...let's take the plunge without a parachute.

00:58

If life were discovered on Mars, as (D) claims, then we probably would've heard about it.

01:04

Unless the government staged a big cover-up.

01:06

Whatever the case, choice (D) isn't passage-approved so we can take it out of the running.

01:10

(C) isn't correct either. The passage specifically tells us that the volcanoes of Mars are inactive.

01:15

We can also cross off choice (B), since the passage doesn't say anything about Mars

01:19

having an unusually high gravitational field. Answer (A) is correct. Lines 46 through 49

01:25

01:29

The discovery of water would be great for all those Martians who've really been needing a shower.
