One group of Facebook friends that Mark Zuckerberg recently decided were not worth hanging out with were its public shareholders,who expected to cross-examine him (via lawyer) in a Delaware court. 这里 that Mark Zuckerberg recently decided were not worth hanging out with were 是不是一个定语从句,是的话,hang out with 后面的宾语是啥? 请大神解答 谢谢
