Meaning: "abnormal" means not normal.

Wrong options:

• abnorml: It leaves out the "a". Write "abnormal". Only the exact spelling gets the mark.
• normal: This is the opposite meaning. The sentence needs not-normal.

Correct answer: tumors / tumours

Explanation: Listen again to "origin of lumps called tumors". You need more than one, so add s. You can write "tumors" or "tumours". Both get the mark.

Meaning: "tumors" means lumps that form when cells grow too much.

Wrong options:

• tumour: "tumour" is a close word, but it ends in "ur". The speaker says "tumors", which ends in "rs".

Correct answer: formations

Explanation: Here you hear "creating chunk-like formations". It comes after 'chunk-like', so you need more than one.

Meaning: "formations" means structures or lumps that form in the body.

Wrong options:

• formattions: It adds an extra "t". Write "formations". Only the exact spelling gets the mark.
• formation: "formation" has no "s" at the end. The speaker says "formations", so write the "s".

Correct answer: organ

Explanation: The speaker says "impede the function of various organ systems". It comes before 'systems', so a body part word.

Meaning: "organ" means a body part that does a job for the body.

Wrong options:

• orgon: It has "o" where the word has "a". Write "organ". Only the exact spelling gets the mark.
• organic: "organic" has an extra "ic" at the end. The speaker says "organ".

Correct answer: symptoms

Explanation: You hear "absence of symptoms in the early". It needs a word that shows more than one.

Meaning: "symptoms" means signs of a disease that a person can notice.

Wrong options:

• symtoms: It leaves out the "p". The right spelling is "symptoms". Every letter must be correct to get the mark.
