Meaning: "Theory" means an idea or set of ideas that explain something.

Wrong options:

• theoy: It leaves out the "r". The right spelling is "Theory". Every letter must be correct to get the mark.

Correct answer: affects

Explanation: On the recording you hear "how gravity affects the curvature". You need an action word here, so listen for the word after "gravity".

Meaning: "affects" means makes a change to something.

Wrong options:

• effects: "effects" is a different word that means results, not the action here.
• afects: It leaves out the "f". Write "affects". Only the exact spelling gets the mark.

Correct answer: verified

Explanation: Listen again to "has been verified through". This already happened, so the word ends in ed.

Meaning: "verified" means checked and shown to be true.

Wrong options:

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

Correct answer: beyond

Explanation: Here you hear "extend beyond physics". The word comes after "extend", so you need a word for place or limit.

Meaning: "beyond" means past or outside a certain area or idea.

Wrong options:

• beyound: It adds an extra "u". Check the letters: "beyond". A small spelling mistake loses the mark.
