Meaning: "underneath" means below something.

Wrong options:

• under neath: This splits the word in two. It is one word. The right spelling is "underneath". Every letter must be correct to get the mark.
• beneath: This is a different word. The sentence needs the exact word heard here.

Correct answer: evaporation

Explanation: Here you hear "returns to the atmosphere through evaporation". You need a word for water turning to gas, it ends in ion.

Meaning: "evaporation" means water changing into vapour or gas.

Wrong options:

• evaporaton: It leaves out the "i". The right spelling is "evaporation". Every letter must be correct to get the mark.
• transpiration: This names water loss from plants, not the general change to gas heard here.

Correct answer: infrastructure

Explanation: The speaker says "Proper infrastructure is necessary to manage water". It comes after "Proper", so you need a word for systems or networks.

Meaning: "infrastructure" means the systems and facilities used to deliver water.

Wrong options:

• infrastrucure: It leaves out the "t". Check the letters: "infrastructure". A small spelling mistake loses the mark.
