Meaning: "technologies" means new methods or tools used in science.

Wrong options:

• technolgies: It leaves out the "o". Write "technologies". Only the exact spelling gets the mark.
• technology: "technology" is a close word, but it ends in "y". The speaker says "technologies", which ends in "ies".

Correct answer: compatible

Explanation: On the recording you hear "environmentally compatible way". You need a describing word, not forgetting the ible ending.

Meaning: "compatible" means able to work without harm together.

Wrong options:

• compatable: It has "a" where the word has "i". The right spelling is "compatible". Every letter must be correct to get the mark.
• incompatible: This is the opposite meaning and does not fit here.

Correct answer: products

Explanation: Listen again to "chemical processes and chemical products". The sentence needs a word for things made, more than one.

Meaning: "products" means materials or items produced by chemical work.

Wrong options:

• produts: It leaves out the "c". Check the letters: "products". A small spelling mistake loses the mark.
• product: "product" has no "s" at the end. The speaker says "products", so write the "s".

Correct answer: fundamental

Explanation: Here you hear "covered fundamental research work". The sentence needs a describing word, not an s at the end.

Meaning: "fundamental" means basic and very important.

Wrong options:

• fundemental: It has "e" where the word has "a". The right spelling is "fundamental". Every letter must be correct to get the mark.
• fundamentals: "fundamentals" has an extra "s" at the end. The speaker says "fundamental", with no "s".

Correct answer: understanding

Explanation: The speaker says "public understanding of the project". You need a word for knowledge or awareness.

Meaning: "understanding" means the knowledge people have about something.

Wrong options:

• understaning: It leaves out the "d". Check the letters: "understanding". A small spelling mistake loses the mark.
