Meaning: "entirely" means completely.

Wrong options:

• entireally: It adds an extra "al". The right spelling is "entirely". Every letter must be correct to get the mark.
• entire: "entire" is missing the ending. The speaker says "entirely", with "ly" at the end.

Correct answer: matter

Explanation: Here you hear "where matter stops." You need a word for the stuff things are made of.

Meaning: "matter" means physical substance or material.

Wrong options:

• materr: It leaves out the "t" and it adds an extra "r". Write "matter". Only the exact spelling gets the mark.

Correct answer: extreme

Explanation: The speaker says "at the extreme temperature." You need a describing word before temperature.

Meaning: "extreme" means very far from normal in degree.

Wrong options:

• extream: It adds an extra "a" and it leaves out the "e". Check the letters: "extreme". A small spelling mistake loses the mark.
• extensive: That word means large in size, not very high or low in degree.

Correct answer: frozen

Explanation: You hear "stayed frozen in the sodium." After 'stayed' you need a describing word, it ends in en.

Meaning: "frozen" means turned hard and not moving like ice.

Wrong options:

• frosen: It has "s" where the word has "z". Check the letters: "frozen". A small spelling mistake loses the mark.
• freeze: That is the action. The sentence needs a describing word, not the action.

Correct answer: original

Explanation: Listen for "the original light." "original" comes after 'the', so it means the first one.

Meaning: "original" means the first or the same as before.

Wrong options:

• orginal: It leaves out the "i". The right spelling is "original". Every letter must be correct to get the mark.
• originally: "originally" has an extra "ly" at the end. The speaker says "original".

Correct answer: converted

Explanation: On the recording you hear "was converted back." You need the past form with ed.

Meaning: "converted" means changed from one form into another.

Wrong options:

• convertid: It has "i" where the word has "e". Check the letters: "converted". A small spelling mistake loses the mark.
• convert: "convert" is missing the ending. The speaker says "converted", with "ed" at the end.

Correct answer: communications

Explanation: Listen again to "fiber optic communications." You need more than one, so the word ends in s.

Meaning: "communications" means systems that send information.

Wrong options:

• comunications: It leaves out the "m". Write "communications". Only the exact spelling gets the mark.
• communication: "communication" has no "s" at the end. The speaker says "communications", so write the "s".
