Meaning: "orbit" means to move around something in space.

Wrong options:

• oribt: Two letters are in the wrong order. The right spelling is "orbit". Every letter must be correct to get the mark.
• orbits: "orbits" has an extra "s" at the end. The speaker says "orbit", with no "s".

Correct answer: solve

Explanation: Listen for "help them to solve" You need an action word that means find an answer.

Meaning: "solve" means to find the answer to a problem.

Wrong options:

• solv: It leaves out the "e". Check the letters: "solve". A small spelling mistake loses the mark.
• solved: "solved" has an extra "d" at the end. The speaker says "solve".

Correct answer: launched

Explanation: On the recording you hear "first satellite launched" This already happened, so the word ends in ed.

Meaning: "launched" means sent into space for the first time.

Wrong options:

• launced: It leaves out the "h". Write "launched". Only the exact spelling gets the mark.
• launch: "launch" is missing the ending. The speaker says "launched", with "ed" at the end.

Correct answer: greatly

Explanation: Listen again to "added greatly to" It tells how much, ends in ly.

Meaning: "greatly" means to a large extent or amount.

Wrong options:

• greately: It adds an extra "e". Write "greatly". Only the exact spelling gets the mark.
• great: "great" is missing the ending. The speaker says "greatly", with "ly" at the end.

Correct answer: figure

Explanation: Here you hear "helped figure out" It comes after "helped", so an action word follows.

Meaning: "figure" means to find an answer or understand something.

Wrong options:

• figer: It has "e" where the word has "u" and it leaves out the "e". Write "figure". Only the exact spelling gets the mark.
• figured: "figured" has an extra "d" at the end. The speaker says "figure".
