Meaning: "flooding" means seawater rising and covering land.

Wrong options:

• floodin: It leaves out the "g". Write "flooding". Only the exact spelling gets the mark.
• floding: It leaves out the "o". The right spelling is "flooding". Every letter must be correct to get the mark.

Correct answer: migration

Explanation: Listen again to "the migration of certain". The sentence needs a word for movement of animals.

Meaning: "migration" means animals moving from one place to another.

Wrong options:

• migraton: It leaves out the "i". The right spelling is "migration". Every letter must be correct to get the mark.
• emigration: This is a different idea about people leaving a country, not animal movement here.

Correct answer: protective

Explanation: Here you hear "development of protective barriers". You need a describing word that comes before barriers.

Meaning: "protective" means made to keep something safe from harm.

Wrong options:

• proective: It leaves out the "t". Check the letters: "protective". A small spelling mistake loses the mark.
• protecting: "protecting" is a close word, but it ends in "ng". The speaker says "protective", which ends in "ve".

Correct answer: storm

Explanation: The speaker says "against storm surges". You need a word for a strong sea weather event.

Meaning: "storm" means a strong weather event with wind and heavy rain at sea.

Wrong options:

• stom: It leaves out the "r". The right spelling is "storm". Every letter must be correct to get the mark.
• stormy: "stormy" has an extra "y" at the end. The speaker says "storm".
