第一句的主语是the dietitian ,它的谓语就是works,因为the dietitian 是第三人称单数,所以用works,而who is cooking the meal 是修饰the dietitian 既是作为定语部分,对于第一句来说,句子的主干是the dietitian （who is cooking the meal） works for the museum,不要看括号那部分,括号那部分只是修饰the dietitian.你试想一下,如果一个句子是
the dietitian _____for the museum,横线上要你填work的一个正确形式,相信根据A dietitian is cooking the meal.She works for the museum 这个原句的第2句,你会很自然地在横线上填上works而不是is works吧?更何况没有这样的一种形式!
至于第二个,在定语从句 which is advertised in the paper 中,which是这个句子的主语,which指代的正是the movie,那试问,电影是被人做广告,做宣传,还是自己做广告,做宣传?因为电影是一个物体,它自己不能advertise,只能被人advertise,所以这个地方要用被动形式,而被动形式的结构式be动词+动词的过去分词,用到上文正是is+advertised（advertise的过去分词）,所以才要加is,这个is的用意是形成被动结构!
在定语从句中选择动词的正确形式一般要取决于对应的主语或宾语在所在的句子中是不是主动,如果是被动需要用被动形式,如果是第三人称单数则要选用对应的第三人称单数.

第一句
the dietitian (who is cooking the meal) works for the museum.相当于把原来的第一句插到第二句的主语后面，只是把a dietitian 换成了 who，把括号里去掉就是原来的第二句。
第二句
你给的原句本来就是定语从句，只不过which is省略掉了。
也是同样的道理the movie （which is advertised in the paper） is shown on weekdays ，把两个句子并起来，which指代the movie。你可以看一下，把括号里的去掉，就是一句被动句子。

第一句主语和谓语之间是主动关系而第二局是被动关系
