Here is the correct matching of definitions to words:
- the horizontal mark used to indicate a stressed syllable in a foot of verse - macron
- the way in which a word or sound is spoken - pronunciation
- a stock of words used and understood - vocabulary
- emphasis or stress placed on a syllable or word - accent
- a notice designed to attract public notice or patronage - advertisement
- a curved diacritical mark used to indicate an unstressed syllable or a short vowel - breve
- a number of picked flowers tied together in a bunch - bouquet
- marking a distinction - diacritical
- the operation of aircraft - aviation
- the science of life and living organisms - biology
Please note that the matching for number 1 should actually be "diacritical mark" (the general term) while "macron" is specifically referring to the horizontal mark, but based on your lists, it seems the intention was to just match them directly.
