Meaning: "permanent" means lasting for a long time.

Wrong options:

• permanently: "permanently" has an extra "ly" at the end. The speaker says "permanent".

Correct answer: frustrated

Explanation: You hear "She's frustrated that scientists". It is a feeling word and it ends in ed.

Meaning: "frustrated" means annoyed or upset because things are not changing.

Wrong options:

• frustated: It leaves out the "r". Write "frustrated". Only the exact spelling gets the mark.
• frustrating: "frustrating" is a close word, but it ends in "ing". The speaker says "frustrated", which ends in "ed".

Correct answer: emit

Explanation: Listen for "Australia will emit just over". It needs an action word after will, the plain word.

Meaning: "emit" means to give out or send out, like gas or carbon.

Wrong options:

• emmit: It adds an extra "m". Write "emit". Only the exact spelling gets the mark.
• omit: "Omit" means to leave out, not to give out or produce.

Correct answer: increasing

Explanation: On the recording you hear "by increasing soil carbon by". After by you need an action word that ends in ing.

Meaning: "increasing" means making something larger or higher.

Wrong options:

• increacing: It has "c" where the word has "s". Check the letters: "increasing". A small spelling mistake loses the mark.
• increase: "increase" is a close word, but it ends in "e". The speaker says "increasing", which ends in "ing".

Correct answer: whole

Explanation: Listen again to "sequester the whole world's emissions". It comes before world's and means the entire amount.

Meaning: "whole" means all or entire, nothing left out.

Wrong options:

• wholle: It adds an extra "l". Write "whole". Only the exact spelling gets the mark.
• hole: "Hole" is an opening or gap and does not mean entire or complete.
