"What did you do last weekend?"
了 is pronounced as liao3 in phrases like 了解 and 了不起. In this sentence it should be pronounced le, though.
I've noticed before when tapping the single 了 tile, the male voice pronounces it as le, whereas the female voice pronounces it as liao3.
(This is obviously unrelated, but I like your 4341 day streak. :) Have a lingot for it!)
Particles 了 le and 过 guò to indicate past action. I FINALLY found a resource that explained it. - https://www.digmandarin.com/all-video-lessons/grammar-summary-le-chinese and https://www.digmandarin.com/use-le-in-chinese.html
