Meaning: "killer" means a kind of large whale.

Wrong options:

• kiler: It leaves out the "l". The right spelling is "killer". Every letter must be correct to get the mark.
• killers: "killers" has an extra "s" at the end. The speaker says "killer", with no "s".

Correct answer: enormity

Explanation: Listen for "through the enormity of the". It comes after "the", so you need a word for a thing.

Meaning: "enormity" means great size or scale over time.

Wrong options:

• enormaty: It has "a" where the word has "i". Write "enormity". Only the exact spelling gets the mark.
• enormous: "enormous" is a close word, but it ends in "ous". The speaker says "enormity", which ends in "ity".

Correct answer: basically

Explanation: On the recording you hear "we have basically a". You need a word that tells how or how much, so it ends in ly.

Meaning: "basically" means in simple terms or in general.

Wrong options:

• basicly: It leaves out the "al". Check the letters: "basically". A small spelling mistake loses the mark.
• basical: "basical" is missing the ending. The speaker says "basically", with "ly" at the end.

Correct answer: bigger

Explanation: Listen again to "a dolphin, a bigger brain with". The sentence compares size, so the word ends in er.

Meaning: "bigger" means larger in size.

Wrong options:

• biger: It leaves out the "g". Check the letters: "bigger". A small spelling mistake loses the mark.
• big: This does not compare. The sentence needs a comparing word.
