Which event happened third?

puritan preachers opposed both new theaters.
the theatre was built by brayne and burbage at shoreditch.
the curtain, a second theater in the area, was built.
city authorities were given powers to place restrictions on playhouses.

The answer is D: City authorities were given powers to place restrictions on playhouses.  The first playhouse built by Brayne and Burgage, in 1576, was The Theather. After one year, the second playhouse was built, The Curtain, in the same district of Shoreditch.  In 1584, the city of London asked the district to close their playhoses. But there is no evidence that this petition had achieved its goal.
