Meaning: "detect" means find or notice.

Wrong options:

• detekt: It has "k" where the word has "c". Check the letters: "detect". A small spelling mistake loses the mark.

Correct answer: flying

Explanation: Here you hear "when the bats were flying". It comes after "were", so the word ends in ing.

Meaning: "flying" means moving through the air.

Wrong options:

• flyng: It leaves out the "i". The right spelling is "flying". Every letter must be correct to get the mark.

Correct answer: measured

Explanation: The speaker says "It also measured the fact". This already happened, so the word ends in ed.

Meaning: "measured" means checked or recorded.

Wrong options:

• mesured: It leaves out the "a". The right spelling is "measured". Every letter must be correct to get the mark.
• measures: "measures" is a close word, but it ends in "s". The speaker says "measured", which ends in "d".

Correct answer: object

Explanation: You hear "closer to an object they". It comes after "an", so you need a word for a thing.

Meaning: "object" means a thing or item.

Wrong options:

• obect: It leaves out the "j". Write "object". Only the exact spelling gets the mark.

Correct answer: inner

Explanation: Listen for "cells in the inner ears". It comes before "ears", so you need a word meaning inside.

Meaning: "inner" means inside or near the centre.

Wrong options:

• internal: Internal is different. The recording used 'inner'.

Correct answer: multiple

Explanation: On the recording you hear "in multiple ways." You need a word that means more than one.

Meaning: "multiple" means more than one.

Wrong options:

• mutiple: It leaves out the "l". Write "multiple". Only the exact spelling gets the mark.
