[Tdol]

'Sore' and 'ache' have different meanings but function differently; the former an adjective, the latter a suffix, and they may well ask about when to use them. There might be a problem with the indefinite article usage; why use it when we only have one head, one throat, and why is 'cough' in the singular when it can have a plural and 'a cough' is usually characterised by coughing moire than once. Also, they might use different verbs in L1.
