Unlocking the phone, opening an app, scrolling through a track list, tapping a specific song.

Those are all things that could distract a driver.

There has been previous research into things like this, whether certain days can correlate to more danger on the road.

Past studies, for example, have shown that traffic deaths have been higher than usual on tax day, which is next week, possibly because of stress and distractions.

And I'll see you next time.

Now, time for the quiz.

Every week, we ask you a few questions about stories The Times has been covering.

Can you get them all?

First up.

For years, there's been an enormous mystery swirling about the true identity of the creator of one of the most influential inventions of the 21st century.

This week, the Times published a new investigation with evidence suggesting that the figure who went by the name of Satoshi Nakamoto is a 55-year-old British man named Adam Back.

Your question, what is the invention?

The answer?

Bitcoin.

Yeah.

Despite the fact that it's become a trillion-dollar-plus industry, the inventor of it has never claimed credit, which has led to all the speculation.

If Bak is in fact Satoshi, which he denies, he could quietly be one of the richest people on Earth, potentially holding a stash of Bitcoin worth nearly $80 billion.

And second question.

Recently, footage hit the press of a classic parenting moment.
