Visual computing researchers at the University of Bradford in the U.K. started with software for a changing facial expression. This program can examine a video clip of a human head and identify specific around the eyes, cheeks and mouth. Then the program tracks the details moving relative to each other as the face smiles. Next, the scientists had their program two sets of video clips. In one, subjects performed posed smiles.

Correct answer: being
Explanation: Here you hear "are they just being polite". It follows "just", so the word ends in ing.
Meaning: "being" means existing in that state.
Wrong options:
- beeing: It adds an extra "e". Write "being". Only the exact spelling gets the mark.
- been: "been" has no ing. The sentence needs a word that shows a continuing state.
Correct answer: fake
Explanation: The speaker says "distinguish a fake grin from". The word comes before "grin", so you need a describing word.
Meaning: "fake" means not real.
Wrong options:
- fak: It leaves out the "e". Write "fake". Only the exact spelling gets the mark.
- fakes: "fakes" has an extra "s" at the end. The speaker says "fake", with no "s".
Correct answer: develop
Explanation: You hear "until researchers develop a program". After "researchers" you need an action word, the plain word.
Meaning: "develop" means to build or make something new.
Wrong options:
- develope: It adds an extra "e". Write "develop". Only the exact spelling gets the mark.
- developed: "developed" has an extra "ed" at the end. The speaker says "develop".
Correct answer: simulating
Explanation: Listen for "software for simulating a changing facial". The word must be an action word and ends in ing.
Meaning: "simulating" means copying how something changes or behaves.
Wrong options:
- simulatin: It leaves out the "g". The right spelling is "simulating". Every letter must be correct to get the mark.
- simulate: "simulate" is a close word, but it ends in "e". The speaker says "simulating", which ends in "ing".
Correct answer: details
Explanation: On the recording you hear "identify specific details around the". The word comes after "specific", so do not forget the s at the end.
Meaning: "details" means small parts or features.
Wrong options:
- detales: It leaves out the "i" and it adds an extra "e". Write "details". Only the exact spelling gets the mark.
- detail: "detail" has no "s" at the end. The speaker says "details", so write the "s".
Correct answer: analysing / analyzing
Explanation: Listen again to "had their program analysing two sets". After "program" the sentence calls for an action word ending in ing. You can write "analysing" or "analyzing". Both get the mark.
Meaning: "analysing" means examining carefully to find patterns or meaning.
