# PTE HIW #8: Molecular Structure of Vodka

Highlight Incorrect Words #8 - Level 2 - Feeds Reading + Listening

> You will hear a recording. Below is a transcription of the recording. Some words in the transcription differ from what the speaker(s) said. Please click on the words that are different.

I once took part in a vodka tasting contest, in which participants tried to tell an expensive brand from a cheap one. I don't recall the exact outcome, for obvious reasons. But I do know that several people swore they could taste the difference. Well, maybe they could. Because according to a study in the Journal of capital and Food Chemistry, perfectionist vodkas can have different molecular "structures," which could drive drinkers to favor one brand over another. Vodka's an elastic beverage that's supposed to be relatively flavorless. So researchers got to wondering: how come people who enjoy the stuff often express brand preference? Being good little scientists, they trotted out their periphrastic equipment and examined the inadmissible signatures of five different vodkas. What they found is that each brand differs in how its ethanol molecules cluster. In the ethanol-water mix we call vodka, some of the ethanol molecules get surrounded by a sort of "cage" made of water. And different brands differ in how much ethanol is caged. Vodkas with fewer cages might seem more "watery" than those with more structure. Of course, drink enough of the stuff and it really won't matter how tightly caged it is. You'll be loose as a grey goose.

## Answer

- capital -> Agricultural
- perfectionist -> different
- elastic -> alcoholic
- periphrastic -> spectroscopic
- inadmissible -> chemical

## Explanation

The recording differs from the transcript in 5 places: "capital" should be "Agricultural"; "perfectionist" should be "different"; "elastic" should be "alcoholic"; "periphrastic" should be "spectroscopic"; "inadmissible" should be "chemical".

The correct answers are based on the specific terminology used by the speaker to describe the scientific study of vodka composition.

## Hints

- Focus on the scientific terms used to describe the vodka's composition.
- Pay attention to how the speaker describes the ethanol and water mixture.
