Final answer:
The adverb that best completes the sentence is 'cariñosamente' which means 'lovingly' in English.
Step-by-step explanation:
The adverb that best completes the sentence is cariñosamente which means 'lovingly' in English. Eduardo is saving money in order to travel around Ecuador, so it makes sense to use an adverb that describes his actions with affection or love. Some other possible options like 'fuertemente' (strongly) or 'especialmente' (especially) are not as appropriate in this context because they do not convey the same meaning as 'cariñosamente'.
