Meaning: "emissions" means gases released into the air.

Wrong options:

• emisions: It leaves out the "s". The right spelling is "emissions". Every letter must be correct to get the mark.
• emission: "emission" has no "s" at the end. The speaker says "emissions", so write the "s".

Correct answer: fuels

Explanation: On the recording you hear "dependence on fossil fuels". It comes after "fossil", so you need more than one and do not forget the s.

Meaning: "fuels" means materials like coal or oil used for energy.

Wrong options:

• fuel: "fuel" has no "s" at the end. The speaker says "fuels", so write the "s".

Correct answer: pollutants

Explanation: Listen again to "releasing harmful pollutants". The sentence needs a word for bad things in the air, and it ends in s.

Meaning: "pollutants" means harmful substances that dirty the air.

Wrong options:

• pollutant: "pollutant" has no "s" at the end. The speaker says "pollutants", so write the "s".
• pollutents: It has "e" where the word has "a". The right spelling is "pollutants". Every letter must be correct to get the mark.

Correct answer: development

Explanation: Here you hear "promotes sustainable development". It comes after "sustainable", so you need a word for growth that ends in ment.

Meaning: "development" means the process of growing or improving over time.

Wrong options:

• developement: It adds an extra "e". The right spelling is "development". Every letter must be correct to get the mark.
• developing: "developing" is a close word, but it ends in "ing". The speaker says "development", which ends in "ment".
