Meaning: "exploded" means grew very fast or spread out quickly.

Wrong options:

• exploaded: It adds an extra "a". Check the letters: "exploded". A small spelling mistake loses the mark.
• expanded: This is a different word. The speaker uses a stronger idea than expanded.

Correct answer: low-density

Explanation: You hear "into low-density suburbia". The phrase needs the hyphenated describing word low-density.

Meaning: "low-density" means with few people or buildings over a large area.

Wrong options:

• low density: It has " " where the word has "-". The right spelling is "low-density". Every letter must be correct to get the mark.
• high-density: This is the opposite idea and so is not correct here.

Correct answer: residents

Explanation: Listen for "a third fewer residents than". The missing word names the people living there, residents.

Meaning: "residents" means the people who live in a place.

Wrong options:

• residants: It has "a" where the word has "e". The right spelling is "residents". Every letter must be correct to get the mark.
• residence: "residence" is a close word, but it ends in "ce". The speaker says "residents", which ends in "ts".

Correct answer: distinction

Explanation: On the recording you hear "the very distinction between urban". The sentence needs the word distinction.

Meaning: "distinction" means the clear difference between two things.

Wrong options:

• distincton: It leaves out the "i". The right spelling is "distinction". Every letter must be correct to get the mark.
• distinctive: "distinctive" is a close word, but it ends in "ve". The speaker says "distinction", which ends in "on".

Correct answer: disappeared

Explanation: Listen again to "has all but disappeared as". The word shows something has nearly gone, disappeared.

Meaning: "disappeared" means stopped existing or is no longer seen.

Wrong options:

• dissappeared: It adds an extra "s". Write "disappeared". Only the exact spelling gets the mark.
