Explicación
1: an adjective before 'work': 'voluntary work' ('volunteer work' does not change the word). 2: noun after 'the main': 'attraction'. 3: adverb before the adjective 'critical': 'increasingly'. 4: noun after 'the necessary': 'qualifications' (the singular is also accepted). 5: the work 'has to be done again', so the visitors lack skill: negative adjective 'unskilled' – 'skilled' or 'skilful' give the opposite meaning. 6: adjective after 'be': 'harmful'. 7: noun after 'careful': 'planning' ('plan' is unchanged; 'plans' does not fit 'careful … can benefit'). 8: plural noun, because the verb is 'are spent': 'donations'.
