Meaning: "confirmed" means proved to be true.

Wrong options:

• confrimed: Two letters are in the wrong order. Write "confirmed". Only the exact spelling gets the mark.
• confirm: "confirm" is missing the ending. The speaker says "confirmed", with "ed" at the end.

Correct answer: chemical

Explanation: Listen for "the psychology laboratory even as chemical laboratory". It comes before "laboratory", so you need the word for chemistry.

Meaning: "chemical" means about chemistry or chemicals.

Wrong options:

• chemcial: Two letters are in the wrong order. Write "chemical". Only the exact spelling gets the mark.
• chemistry: "chemistry" is a close word, but it ends in "stry". The speaker says "chemical", which ends in "cal".

Correct answer: realities

Explanation: On the recording you hear "deals with the realities of the supermind". It comes after "the", so you need more than one and do not forget the s.

Meaning: "realities" means actual things or truths.

Wrong options:

• realties: It leaves out the "i". Check the letters: "realities". A small spelling mistake loses the mark.
• reality: "reality" is a close word, but it ends in "y". The speaker says "realities", which ends in "ies".

Correct answer: speculative

Explanation: Listen again to "have all in their day been merely speculative". It is a describing word that ends in ive.

Meaning: "speculative" means based on ideas not proved yet.

Wrong options:

• speculitive: It has "i" where the word has "a". Write "speculative". Only the exact spelling gets the mark.
• speculation: "speculation" is a close word, but it ends in "on". The speaker says "speculative", which ends in "ve".
