定位线索：题干“What have studies found about boredom”→答案句取自第1段“Studies point to how boredom is good for creativity and innovation”；文中“linked to innovative thinking”对应选项A“facilitates innovative thinking”。
解析：题干问研究发现无聊有何作用，答案句直接指出无聊与创新思维相关，“linked to innovative thinking”即选项A“facilitates innovative thinking”的同义转述。选项B“doing boring tasks”是研究过程而非结果，偷换概念；选项D与原文“good for mental health”相反，无中生有。
