BBC:New pre-eclampsia test for pregnant women-2

We're now going to independent Pre-eclampsia: NHS to roll out breakthrough test, which speeds up diagnosis and can save lives. 

Roll out, make a service or product widely available. Okay, so this is a phrasal verb, if I'm not mistaken. 

You're not mistaken, Dan. It's a phrasal verb roll plus prepostion out. Um, if you roll something out, it's a separable phase, phrasal verb, so you can roll out somehting. 

Mm-hmm.

Um, and it's used in a business and marketing context, um, and it means to launch a product or service, you make it widely available. 

You promote it, you advertise it, you distribute it. So, um, companises often talk about the roll out of a new product, new, os. 

A new mobile phone, for example. Yeah. They roll out the mobile phone or they roll the mobile phone out. 

Absolutely. Both are correct and you, it means that they're. Phone will be promoted. 

You'll see advertising, you'll see discount offers. It'll be avaiable in the shops. It just means to make it available. 

Okay. Now, um, again, going back to the cooking and the cakes, uh, when you use a rolling pink, you roll out the dough. Is it, are they, are they connected. 

When you Yeah. You make paste. 

Kind of flatten it and spread it everywhere?

Yeah. Is it, are they connected at all?

Not really, no. 

But it might help you to remember if you think of the dough getting bigger and bigger and spreading and spreading. 

Okay, so like the product, it goes everywhere. 

Yeah, exactly. That useful to useful memory device if it nothing works better. If it works for you. 

Exactly. Nothing works better for vocabulary than cake, so. 

There you go. That is a win-win.

Thank you very much. So before we go to our vocabulary recap, let's roll out our social media challenge. Now, this morning we posted a magnificent picture of a snake with the following. Complete this sentence, be careful. One bite from this snake can- fatal. And then we gave three options. A. Make, B. Cause, or C. Prove. 

What's the correct answer, Catherine? And how did they do?

Well done. I think you got. A lot of people caught them out at this time. Yeah, because, um, a lot of people said, cause option B, a few people said A make, but not many people said, C, prove, which is the correct answer. If something proves fatal, it eventually.

We'll kill you. Um, and preeclampis proves fatal in a lot of women. Um, so yeah, prove fatal. Not many people got it right. But if you are on Instagram, Hasina shabnam on Facebook for what? Hussein or on Twitter? Isha. You guys got it right? And a few other people did as well. So well done if you were one of them. 

Well done to everybody who got it correct. So can we please have our vocabulary recap?

Most certainly. We had imprecise: not accurate or exact, -to-be: happening or becoming in the future and roll out: make a service or product widely available.
