I have a french sentence. I don't understand why it has no correlation with subject. 1) Les petites filles se sont lavé les mains avant de venir à table 2) Les petites filles se sont lavées les mains avant de venir à table In the book I see that 1st is correct, 2nd is my opinion. Which one is correct?

How I've broken the collarbone. Recently I was doing freesbee with my mates and nothing seemed to be wrong that day... But unluckily I run into another player miscalculating opponent's track on the field. I was running like mad with maximum speed and believed that I can get the disk, so did the player from the other team. We crashed, fell on the grass, felt terrible pain. Somebody had screamed that freesbee is non-contact sport and badly sweared showing his annoyance of that terrible play. I don't know the damage that got another player, but I hope he's doing fine. At that moment I was totally concentrated on the sting pain in my shoulder. I had asked captain to be replaced and moved out of the playing-zone. Several minutes later pain hadn't dissapeared and I decided to move to the nearest emergency station suspecting bone fracture... Broken right collarbone(fortanatelly without displacement)... At least 5 weeks of arm immobilization... It would be 'increadibly interresting' summer for me...

'great' meaning very big Hi. Today I had a conflict with my college, because he said that 'great' doesn't sound right in the sentence: 'We have great problems'. I use it very often in meaning 'very big' or 'huge'? So is it correct to say so or I’d better pick other adjective?

Grammar question. Is it grammatically correct to say : 1) "I demanded him to apologise" instead of "I demanded that he apologise" 2) "It's essential that everyone is here on time" instead of "it's essential that everyone be here on time" Second sentences are taken from the book, so they should be correct
