Meaning: "categorise" means to put things into groups.

Wrong options:

• catagorise: It has "a" where the word has "e". Check the letters: "categorise". A small spelling mistake loses the mark.

Correct answer: sociologist

Explanation: The speaker says "political philosopher, sociologist, jurist". It comes between two jobs, so you need a person word.

Meaning: "sociologist" means a person who studies how people live in groups.

Wrong options:

• sociologest: It has "e" where the word has "i". The right spelling is "sociologist". Every letter must be correct to get the mark.
• psychologist: This is a different kind of expert, not the one named here.

Correct answer: letters

Explanation: You hear "the Persian Letters a novel". After "Persian" the title uses a word for more than one thing.

Meaning: "letters" here means written pieces collected as a book.

Wrong options:

• letter: "letter" has no "s" at the end. The speaker says "letters", so write the "s".

Correct answer: influence

Explanation: Listen for "have had the most influence on". You need a word for effect or power on others.

Meaning: "influence" means the effect someone has on later thinkers.

Wrong options:

• influance: It has "a" where the word has "e". The right spelling is "influence". Every letter must be correct to get the mark.

Correct answer: customs

Explanation: On the recording you hear "variety of morals, customs, ideas". It sits between morals and ideas, so more than one is needed.

Meaning: "customs" means the usual ways people behave in a place.

Wrong options:

• costums: Two letters are in the wrong order. Check the letters: "customs". A small spelling mistake loses the mark.
• custom: "custom" has no "s" at the end. The speaker says "customs", so write the "s".
