Meaning: "automation" means control by machines.

Wrong options:

• automaiton: Two letters are in the wrong order. Write "automation". Only the exact spelling gets the mark.
• automaton: "automaton" is a close word, but it ends in "on". The speaker says "automation", which ends in "ion".

Correct answer: efficient

Explanation: Listen again to "create seamless, efficient living". You need a word that describes, not one ending in ly.

Meaning: "efficient" means working well with little waste.

Wrong options:

• effecient: It has "e" where the word has "i". The right spelling is "efficient". Every letter must be correct to get the mark.
• efficiently: "efficiently" has an extra "ly" at the end. The speaker says "efficient".

Correct answer: comprehensive

Explanation: Here you hear "offers a comprehensive solution that controls". The word is before "solution", so pick a word meaning very complete.

Meaning: "comprehensive" means very complete.

Wrong options:

• comprehesive: It leaves out the "n". Write "comprehensive". Only the exact spelling gets the mark.
• comprehension: "comprehension" is a close word, but it ends in "on". The speaker says "comprehensive", which ends in "ve".

Correct answer: convenience

Explanation: The speaker says "not only enhances convenience but also". The sentence needs a word for a thing, so use the form that ends in ence.

Meaning: "convenience" means making things easier.

Wrong options:

• convinience: It has "i" where the word has "e". Check the letters: "convenience". A small spelling mistake loses the mark.
• convenient: "convenient" is a close word, but it ends in "t". The speaker says "convenience", which ends in "ce".

Correct answer: security

Explanation: You hear "savings and security". It follows "and", so you need a word for safety, a thing.

Meaning: "security" means safety and protection.

Wrong options:

• securty: It leaves out the "i". Write "security". Only the exact spelling gets the mark.

Correct answer: ecosystem

Explanation: Listen for "the intelligent home ecosystem". It comes after "home", so you need a word for a connected system.

Meaning: "ecosystem" means a connected group of devices and services.

Wrong options:

• ecosytem: It leaves out the "s". Write "ecosystem". Only the exact spelling gets the mark.
• economy: Economy is about money and markets, not a connected system of devices.
