Meaning: "renewable" means able to be replaced naturally.

Wrong options:

• renwable: It leaves out the "e". Check the letters: "renewable". A small spelling mistake loses the mark.
• renewably: "renewably" is a close word, but it ends in "y". The speaker says "renewable", which ends in "e".

Correct answer: solar

Explanation: The speaker says "solar and wind energy, in particular". It comes before "and", a word for energy from the sun.

Meaning: "solar" means from the sun.

Wrong options:

• soler: It has "e" where the word has "a". Write "solar". Only the exact spelling gets the mark.

Correct answer: wind

Explanation: You hear "solar and wind energy, in particular". It follows "and", a word for power from moving air.

Meaning: "wind" means the moving air used to make energy.

Wrong options:

• windy: "windy" has an extra "y" at the end. The speaker says "wind".

Correct answer: footprint

Explanation: Listen for "reduce our carbon footprint, decrease". It comes after "carbon", a word for a thing that shows impact.

Meaning: "footprint" means the total environmental impact a person or activity makes.

Wrong options:

• foot print: This splits the word in two. It is one word. Write "footprint". Only the exact spelling gets the mark.
• footprints: "footprints" has an extra "s" at the end. The speaker says "footprint", with no "s".

Correct answer: efficiency

Explanation: On the recording you hear "energy efficiency in our homes and workplaces". You need a word that ends in y and talks about saving energy.

Meaning: "efficiency" means using less energy to do the same job.

Wrong options:

• eficiency: It leaves out the "f". The right spelling is "efficiency". Every letter must be correct to get the mark.
• efficient: "efficient" is a close word, but it ends in "t". The speaker says "efficiency", which ends in "cy".

Correct answer: sustainable

Explanation: Listen again to "adopting sustainable practices and advocating". The word describes practices and ends in able.

Meaning: "sustainable" means able to continue without harming the environment.

Wrong options:

• sustanable: It leaves out the "i". Write "sustainable". Only the exact spelling gets the mark.
• sustainably: "sustainably" is a close word, but it ends in "y". The speaker says "sustainable", which ends in "e".
