Meaning: "barriers" means things that stop or block the river.

Wrong options:

• barier: It leaves out the "r" and it leaves out the "s". Check the letters: "barriers". A small spelling mistake loses the mark.
• barrier: "barrier" has no "s" at the end. The speaker says "barriers", so write the "s".

Correct answer: restrict

Explanation: Listen for "built to restrict and control". Following 'built to' the sentence needs an action word.

Meaning: "restrict" means to limit the flow or amount of water.

Wrong options:

• restirct: Two letters are in the wrong order. The right spelling is "restrict". Every letter must be correct to get the mark.
• restricts: "restricts" has an extra "s" at the end. The speaker says "restrict", with no "s".

Correct answer: irrigate

Explanation: On the recording you hear "to irrigate farmland". The word follows 'to', so use the action word 'irrigate'.

Meaning: "irrigate" means to bring water to farm land for crops.

Wrong options:

• irigate: It leaves out the "r". Write "irrigate". Only the exact spelling gets the mark.
• irrigation: "irrigation" is a close word, but it ends in "ion". The speaker says "irrigate", which ends in "e".

Correct answer: droughts

Explanation: Listen again to "risk of floods and droughts". You need a word for more than one, so it ends in s.

Meaning: "droughts" means long periods with little or no rain.

Wrong options:

• drougths: Two letters are in the wrong order. The right spelling is "droughts". Every letter must be correct to get the mark.
• drought: "drought" has no "s" at the end. The speaker says "droughts", so write the "s".

Correct answer: occur

Explanation: Here you hear "flooding can occur in". After 'can' use the plain word 'occur'.

Meaning: "occur" means to happen.

Wrong options:

• ocurr: It leaves out the "c" and it adds an extra "r". Write "occur". Only the exact spelling gets the mark.
• occurs: "occurs" has an extra "s" at the end. The speaker says "occur", with no "s".
