Meaning: "diamond" means a hard, precious stone.

Wrong options:

• diamon: It leaves out the "d". Check the letters: "diamond". A small spelling mistake loses the mark.
• diamnd: It leaves out the "o". Write "diamond". Only the exact spelling gets the mark.

Correct answer: remains

Explanation: Listen again to "from the remains of vegetation". It comes after "the", so you need a word for what was left.

Meaning: "remains" means what was left behind.

Wrong options:

• remainds: It adds an extra "d". Check the letters: "remains". A small spelling mistake loses the mark.
• remained: "remained" is a close word, but it ends in "ed". The speaker says "remains", which ends in "s".

Correct answer: definitely

Explanation: Here you hear "coal and definitely older than". You need a word that tells how or how much, so it ends in ly.

Meaning: "definitely" means surely or without doubt.

Wrong options:

• definately: It has "a" where the word has "i". Check the letters: "definitely". A small spelling mistake loses the mark.
• definite: "definite" is missing the ending. The speaker says "definitely", with "ly" at the end.

Correct answer: originates

Explanation: The speaker says "coal originates in horizontally". After "coal" the sentence needs an action word, so it ends in s.

Meaning: "originates" means starts or comes from.

Wrong options:

• orginates: It leaves out the "i". Write "originates". Only the exact spelling gets the mark.
• originated: "originated" is a close word, but it ends in "d". The speaker says "originates", which ends in "s".

Correct answer: vertical

Explanation: You hear "found in vertical pipes filled". It comes after "in", so you need a describing word, ends in al.

Meaning: "vertical" means straight up and down.

Wrong options:

• verticle: It leaves out the "a" and it adds an extra "e". The right spelling is "vertical". Every letter must be correct to get the mark.
• verticals: "verticals" has an extra "s" at the end. The speaker says "vertical", with no "s".
