Meaning: "cares" means is concerned about something.

Wrong options:

• cars: It leaves out the "e". Check the letters: "cares". A small spelling mistake loses the mark.
• care: "care" has no "s" at the end. The speaker says "cares", so write the "s".

Correct answer: biology

Explanation: You hear "In the field of biology". The phrase "the field of" needs a subject word that ends in y.

Meaning: "biology" means the study of living things.

Wrong options:

• biolgy: It leaves out the "o". The right spelling is "biology". Every letter must be correct to get the mark.
• ecology: This is a different subject. The recording says the bigger subject biology.

Correct answer: respond

Explanation: Listen for "how plants and animals respond to". The sentence needs an action word that ends in d.

Meaning: "respond" means to react or change because of something.

Wrong options:

• responed: It adds an extra "e". Write "respond". Only the exact spelling gets the mark.

Correct answer: experimental

Explanation: On the recording you hear "studies are experimental in nature". It comes after "are", so you need a describing word that ends in al.

Meaning: "experimental" means based on tests and trials.

Wrong options:

• experiemental: It adds an extra "e". Write "experimental". Only the exact spelling gets the mark.
• experiment: "experiment" is missing the ending. The speaker says "experimental", with "al" at the end.
