As vaccination rates rise and governments relax their pandemic ___________. The recovery of the event ecosystem is happening faster than expected. Event management __________ see the number of events and event attendance reaching and potentially ________ pre-pandemic levels in 2019.

'Relaxing' refers to rules, laws, or regulations put in place. Option A is the likely choice. It also correctly refers to 'event management professionals' and 'surpassing pre-pandemic levels'. Option B incorrectly uses the term 'confounding' for 'pre-pandemic levels' and option C uses 'resolutions' which is not the right term to use with 'relax'. Option D also puts the term 'systems' in the first blank, which is incorrect. The best possible choice is option A.
