Meaning: "intensity" means how strong the light is.

Wrong options:

• intencity: It has "c" where the word has "s". Check the letters: "intensity". A small spelling mistake loses the mark.

Correct answer: seeing

Explanation: On the recording you hear "code it is seeing". After "is" the sentence needs an action word that ends in ing.

Meaning: "seeing" means the scanner is reading or noticing the code.

Wrong options:

• seing: It leaves out the "e". Write "seeing". Only the exact spelling gets the mark.
• seen: "seen" is a different form. The sentence needs the action word that ends in ing.

Correct answer: sequentially

Explanation: Listen again to "light sequentially across". The sentence needs a word that tells how, so it ends in ly.

Meaning: "sequentially" means one after another in order.

Wrong options:

• sequentialy: It leaves out the "l". The right spelling is "sequentially". Every letter must be correct to get the mark.
• sequential: "sequential" is missing the ending. The speaker says "sequentially", with "ly" at the end.

Correct answer: translates

Explanation: Here you hear "then translates this pattern". It needs an action word with an s at the end.

Meaning: "translates" means it changes the pattern into a form the computer can use.

Wrong options:

• tranlates: It leaves out the "s". Check the letters: "translates". A small spelling mistake loses the mark.
• translate: "translate" has no "s" at the end. The speaker says "translates", so write the "s".

Correct answer: manipulate

Explanation: The speaker says "able to manipulate data". After "to" the sentence needs the plain word without s.

Meaning: "manipulate" means to handle or work with data.

Wrong options:

• manupulate: It has "u" where the word has "i". The right spelling is "manipulate". Every letter must be correct to get the mark.
• manipulates: "manipulates" has an extra "s" at the end. The speaker says "manipulate", with no "s".
