Wrong options:

• naitve: Two letters are in the wrong order. Check the letters: "native". A small spelling mistake loses the mark.
• natives: "natives" has an extra "s" at the end. The speaker says "native", with no "s".

Correct answer: significantly

Meaning: "significantly" means a lot or importantly.

Wrong options:

• significanly: It leaves out the "t". Check the letters: "significantly". A small spelling mistake loses the mark.
• significant: "significant" is missing the ending. The speaker says "significantly", with "ly" at the end.

Correct answer: rainwater

Explanation: Here you hear "collect rainwater for irrigation". It is one word meaning water from rain.

Meaning: "rainwater" means water that comes from rain.

Wrong options:

• rain water: This splits the word in two. It is one word. Write "rainwater". Only the exact spelling gets the mark.
• rain: "rain" is missing the ending. The speaker says "rainwater", with "water" at the end.

Correct answer: pesticides

Explanation: The speaker says "use of organic pesticides to protect". After "organic" you need a word for things that kill pests, and it ends in s.

Meaning: "pesticides" means chemicals used to kill or stop pests.

Wrong options:

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