Novosibirsk (Kolya) and Vladivostok (Vova)

Novosibirsk (Kolya) and Vladivostok (Vova) were tasked with checking the results of all the cities in order, starting from the east and ending in the south. They've already checked everyone and finally reached the south.

It was 4:03 PM, Vova was rechecking the data he'd already recorded, and Kolya was studying the new results and writing them down. And basically, everything was fine; all the tests were normal, except for some people's blood sugar levels, which were either high or low.

—This time we're doing it really fast.

Vova said, putting another document away in a folder. He looked at Kolya and tensed up a bit. Novosibirsk looked serious; it was clear there was something wrong with the tests he was holding.

• Come on, take a look...

Kolya babbled quietly, Vova began to worry a little, wondering what was there that even Novosibirsk wouldn't understand. Vladivostok picked up the test results and, after reading half of them, was surprised.

—40% radiation?! How is that even possible? Okay, all cities have 10%, but where does the other 30% come from?

Vova was shocked, and Kolya too.

"These are the results from Krasnodar (Daren), but Sochi (Vitya) has only 5%, and Anapa has only 10%, and they're all related. I don't understand why this is so..."

Kolya thought about it. Vrva knew only one thing: he needed to ask Daren himself.

—Maybe we should ask Darren?

Vova suggested it. Kolya nodded in agreement. Vladivostok took out his phone and, finding Krasnodar's number, called him.

• Hello, hi, listen, your tests here aren't going so well, um, well...

Vova didn’t know how to say this, suddenly Darren doesn’t know about it.
