2 There is one mistake in each of the underlined idiomatic expressions in sentences a-f. Look at the relevant dictionary extract and correct the mistake.

Explanation:

This task requires identifying and correcting a mistake in each underlined idiomatic expression. I need to assume which phrases are intended to be underlined, or use common idiomatic expressions to identify potential errors. The provided OCR does not show underlining, so I will identify likely idiomatic phrases and check for common errors or non-idiomatic usage.

Corrected Sentences:

1. a) Di has a young family and runs her own business. She certainly has the hands full. The idiom is 'to have one's hands full', meaning to be very busy. The sentence uses 'has the hands full', which is a minor error in article usage. It should be 'has her hands full'. However, 'certainly' modifies 'has', implying a strong degree of busyness. The phrase 'has the hands full' is not a standard idiom. The correct idiom is 'to have one's hands full'. Therefore, the correction is: 'She certainly has her hands full.'
2. b) Helen is hopeless with money. She's over her neck in debt. The idiom is 'to be over head and ears in debt', meaning to be deeply in debt. 'Over her neck' is incorrect. The correction is: 'She's over head and ears in debt.'
3. c) Petra sometimes makes mistakes but her heart is in its right place. The idiom 'heart is in the right place' means someone is well-intentioned and kind, even if they make mistakes. The phrase 'in its right place' is grammatically correct but 'in the right place' is the standard idiom. The correction is: 'but her heart is in the right place.'
4. d) Sue is always wearing fantastic clothes. She has one eye for fashion. The idiom 'to have an eye for something' means to be good at noticing or judging it. 'One eye' is not the standard idiom. The correction is: 'She has an eye for fashion.'
5. e) Tim's business isn't making much money, but he keeps his head above the water. The idiom 'to keep one's head above water' means to manage to survive, especially financially, in difficult circumstances. This idiom is used correctly. There is no mistake in this sentence's idiom. Let's re-examine the sentence and common idioms. Perhaps the intended mistake is in 'keeps his head above the water'. If the business is *not* making much money, this idiom implies survival. A mistake might be if the intended idiom was something else. However, as it stands, 'keeps his head above the water' is a valid idiom for struggling but surviving. Assuming there must be a mistake, and checking common variants, there might be a typo. However, without further context or the specific
