"Knowledge comes with education."
Translation:Tagann eolas le oideachas.
'Le' prefixes 'h' to words beginning with a vowel in Munster and Ulster. So 'le oideachas' and 'le hoideachas' are both correct.
As this course is based on the Caighdeán, note that the Caighdeán mandates a prefixed h on nouns after le and go (§10.4.1 D.) and on adjectives after le, go, and chomh (§10.4.2 A.).
This translation should have been Tagann an t-eolas leis an oideachas, since both “knowledge” and “education” are abstract nouns that are used in a general sense in the sentence.
eolas is a wider term - "He knows about computers!", whereas fios is a more specific term - "he knows about the meeting".
There are situations where you can use eolas or fios, and there are situations where one is clearly more appropriate than the other.
