Meaning: "supporting" means helping or keeping something working.

Wrong options:

• support: "support" is missing the ending. The speaker says "supporting", with "ing" at the end.
• suporting: It leaves out the "p". The right spelling is "supporting". Every letter must be correct to get the mark.

Correct answer: resources

Explanation: On the recording you hear "competition of resources". After "of" you need a word for things we use.

Meaning: "resources" means supplies or materials people use, like water or energy.

Wrong options:

• resource: "resource" has no "s" at the end. The speaker says "resources", so write the "s".
• resourses: It has "s" where the word has "c". The right spelling is "resources". Every letter must be correct to get the mark.

Correct answer: quality

Explanation: Listen again to "matching the quality of". You need a word for the condition or grade of water.

Meaning: "quality" means how good or clean the water is.

Wrong options:

• qualities: "qualities" is a close word, but it ends in "ies". The speaker says "quality", which ends in "y".
• qualty: It leaves out the "i". Write "quality". Only the exact spelling gets the mark.

Correct answer: systems

Explanation: Here you hear "water systems treat wastewater". After "water" you need a word for a group or network.

Meaning: "systems" means the groups of pipes and plants that manage water.

Wrong options:

• system: "system" has no "s" at the end. The speaker says "systems", so write the "s".
• systms: It leaves out the "e". The right spelling is "systems". Every letter must be correct to get the mark.

Correct answer: underground

Explanation: The speaker says "store it underground before". You need a place word that means under the ground.

Meaning: "underground" means below the earth surface.

Wrong options:

• under ground: This splits the word in two. It is one word. Check the letters: "underground". A small spelling mistake loses the mark.
• underneath: This word is similar but the speaker used one word 'underground' here.
