Meaning: "complex" means not simple, with many parts or characters.

Wrong options:

• complext: It adds an extra "t". Write "complex". Only the exact spelling gets the mark.

Correct answer: authentication

Explanation: Listen again to "multi-factor authentication". You need a word for a method, it ends in tion.

Meaning: "authentication" means checking who someone is, proving identity.

Wrong options:

• authentification: It adds an extra "fi". The right spelling is "authentication". Every letter must be correct to get the mark.
• authorization: This is a different word about permission, not identity checking.

Correct answer: security

Explanation: Here you hear "layer of security". After "of" you need a word for protection.

Meaning: "security" means protection from danger or harm.

Wrong options:

• secuirty: Two letters are in the wrong order. Write "security". Only the exact spelling gets the mark.

Correct answer: attempts

Explanation: The speaker says "recognise phishing attempts". The sentence needs more than one, so it ends in s.

Meaning: "attempts" means tries or efforts, often by attackers.

Wrong options:

• attemps: It leaves out the "t". The right spelling is "attempts". Every letter must be correct to get the mark.
• attempt: "attempt" has no "s" at the end. The speaker says "attempts", so write the "s".

Correct answer: recovered

Explanation: You hear "can be recovered in". It comes after "be", so the word ends in ed.

Meaning: "recovered" means got back or restored after loss.

Wrong options:

• recoved: It leaves out the "re". Write "recovered". Only the exact spelling gets the mark.
• restore: This is a different form of the idea and not the exact word heard.

Correct answer: attack

Explanation: Listen for "event of an attack". It comes after "an", so you need a word for a bad action.

Meaning: "attack" means a harmful action, for example by hackers.

Wrong options:

• attak: It leaves out the "c". Check the letters: "attack". A small spelling mistake loses the mark.
