Meaning: "significantly" means greatly or by a large amount.

Wrong options:

• signficantly: It leaves out the "i". The right spelling is "significantly". Every letter must be correct to get the mark.
• significant: "significant" is missing the ending. The speaker says "significantly", with "ly" at the end.

Correct answer: conservation

Explanation: Listen for "in environmental conservation." It comes after "environmental", so you need a word for a thing.

Meaning: "conservation" means saving and protecting nature.

Wrong options:

• consevation: It leaves out the "r". Check the letters: "conservation". A small spelling mistake loses the mark.
• conversation: Conversation means talking, not protecting nature.

Correct answer: sanctuary

Explanation: On the recording you hear "offer a sanctuary". It comes after a, so you need a word for a place.

Meaning: "sanctuary" means a safe, peaceful place.

Wrong options:

• sactuary: It leaves out the "n". Write "sanctuary". Only the exact spelling gets the mark.
• sanitary: Sanitary means clean, not a safe place.

Correct answer: healthier

Explanation: Listen again to "for a healthier planet." You need a comparing word, so it ends in er.

Meaning: "healthier" means more healthy than before.

Wrong options:

• heathier: It leaves out the "l". Check the letters: "healthier". A small spelling mistake loses the mark.
• healthy: "healthy" is a close word, but it ends in "y". The speaker says "healthier", which ends in "ier".
