Meaning: "glass" means the material used for bottles and jars.

Wrong options:

• glas: It leaves out the "s". Write "glass". Only the exact spelling gets the mark.
• glasses: "glasses" has an extra "es" at the end. The speaker says "glass", with no "es".

Correct answer: sustainability

Explanation: Listen again to "importance of sustainability." The word ends in ity, so check that ending.

Meaning: "sustainability" means long term care of the environment.

Wrong options:

• sustenability: It has "e" where the word has "ai". Check the letters: "sustainability". A small spelling mistake loses the mark.
• sustainable: "sustainable" is a close word, but it ends in "le". The speaker says "sustainability", which ends in "ility".

Correct answer: reduce

Explanation: Here you hear "significantly reduce our". You need an action word, so do not add ed.

Meaning: "reduce" means to make smaller or cut down.

Wrong options:

• reduse: It has "s" where the word has "c". Write "reduce". Only the exact spelling gets the mark.
• reduced: "reduced" has an extra "d" at the end. The speaker says "reduce".

Correct answer: sustainable

Explanation: The speaker says "more sustainable future". It is a describing word, so it 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.
• sustainability: "sustainability" is a close word, but it ends in "ility". The speaker says "sustainable", which ends in "le".
