0:00:12 > 0:00:15Hi, I'm Ayshah and this is your Wednesday afternoon Newsround.
0:00:15 > 0:00:20First, if you've ever shared, liked or commented on something
0:00:20 > 0:00:24on social media, you might want to know about this next story.
0:00:24 > 0:00:27We might not think about it much, but everything we do online builds
0:00:27 > 0:00:31up a picture of our personalities.
0:00:31 > 0:00:34For example who we're friends with on social media
0:00:34 > 0:00:37and when we comment, like or share something.
0:00:37 > 0:00:40Social media companies use this information to make money ?
0:00:40 > 0:00:43they sell it to companies who want to know what we might
0:00:43 > 0:00:46want to buy next, where we might want to go on the weekend,
0:00:46 > 0:00:49or even what new TV shows we might want to watch.
0:00:49 > 0:00:52It's is a big story right now because people are wondering
0:00:52 > 0:00:54whether this information might have helped Donald Trump get elected
0:00:54 > 0:01:01President of the US.
0:01:01 > 0:01:04Ok, it might all sound a bit weird, but bear with us.
0:01:04 > 0:01:06Knowing someone's personality, what they like and what they don't
0:01:06 > 0:01:09like, might tell us more about them ? including, for adults,
0:01:09 > 0:01:13how they might vote in an election.
0:01:13 > 0:01:17And that might help politicians work out how to target particular
0:01:17 > 0:01:20voters over social media. Now it's claimed that a company
0:01:20 > 0:01:23called Cambridge Analytica used information from a Facebook
0:01:23 > 0:01:27personality quiz to find out about the personalities of thousands
0:01:27 > 0:01:31of people who took the quiz.
0:01:31 > 0:01:36They also got info on millions of their online friends as well.
0:01:36 > 0:01:42And it's also been claimed that Cambridge Analytica
0:01:42 > 0:01:43used this information about their personalities
0:01:43 > 0:01:45without their permission to help the campaigns of politicians,
0:01:45 > 0:01:47including Donald Trump.
0:01:47 > 0:01:49But there are rules which mean companies like this should be very
0:01:49 > 0:01:53careful about what they do with our information.
0:01:53 > 0:01:56The claims about Cambridge Analytica and Facebook are now
0:01:56 > 0:01:58being investigated.
0:01:58 > 0:02:01Cambridge Analytica says it didn't do anything wrong and it only uses
0:02:01 > 0:02:07information which has been taken legally and fairly.
0:02:07 > 0:02:10Facebook says it's made changes to try and stop this happening again
0:02:10 > 0:02:17and is also carrying out its own investigation.
0:02:17 > 0:02:19The superstars of the Winter Paralympics, Menna Fitzpatrick
0:02:19 > 0:02:21and her guide Jen Kehoe, have conquered the mountains

0:02:24 > 0:02:30But can they take on our super tough quiz?
0:02:34 > 0:02:37BOTH: Oh...
0:02:37 > 0:02:38I don't know.
0:02:38 > 0:02:45That is tough.
0:02:45 > 0:02:50Disney features quite a lot.
0:02:50 > 0:02:53She's definitely in bed earlier than I am.
0:02:55 > 0:02:57She doesn't believe she snores, but I've actually got the dual
0:02:57 > 0:03:02recording a person ordering.
0:03:02 > 0:03:04-- video recording of her snoring.
0:03:04 > 0:03:05Oh, I don't know.
0:03:05 > 0:03:07I don't think we've seen each other dance that much.
0:03:07 > 0:03:08No.
0:03:08 > 0:03:09Possibly.
0:03:09 > 0:03:10No.
0:03:10 > 0:03:13In absence of a sensible answer, I'm going to back myself!
0:03:16 > 0:03:18Both pretty even.
0:03:18 > 0:03:21I wouldn't like to commit.
0:03:21 > 0:03:23I'd say both of us.
0:03:23 > 0:03:25She follows me, I think that's brave.
0:03:25 > 0:03:27So after our super tough quiz, is there anything they didn't
0:03:27 > 0:03:30know about each other?
0:03:30 > 0:03:32It's thrown up that we need to go dancing together.
0:03:32 > 0:03:36Yeah.
0:03:38 > 0:03:41Next, it's been a big day for this little guy...
