sorry, I have no idea where they came from. They're kind of exercises from my cram school. I'm wondering why we use "approximately" instead of "approximate". And why the first one is "lack" not "without". Though it makes sense to use "lack", there are double verbs in the sentence, isn't it?

第一题bryony兄已经给你指出了programmed to perform a given task是修饰成分而不是谓语。此出明显确谓语。所以选择lack.此处的完整结构应该是Automatons which are programmed to perform a given task .这样不知道你理解了没有？
