my name is greg olsen. i'd like to ask both 9/11 and mr. santos, how free are you independent schools, or what you call them in sweden or franchise or private school that you call in chile, to set compensation and benefits for teachers and other employees of the school system, or i knows that mr. emilsson you mentioned there are unions you deal with. is that a constraint? and then for mr. emilsson, if the independent schools in sweden are doing so well as you pointed out, why then are barely one in 10 of the 11 -- the seven to 16-year-olds enrolled, nine of 10 still in public schools? >> let's take a second first. you know, some rural areas up to 50%, and if you say you only lost 10, 12 years, it really has taken off and expanding rapidly now. the key constraint for opening more schools is difficult to find locations. so we will continue to grow rapidly. yes, we have made a collective agreement with the trade union. and, of course, they will accept as we can increase salaries as we like, but we get the exact same amount as the other monies
