解析：1. 过去式的一般疑问句，谓语动词为一般动词，用助动词did构成一般疑问句，后跟动词原形do，故本题空格处填Did，do。2. 对时间长度提问用多长的疑问短语how long，故本题空格处填How long。3. 被动句的结构为be+动词的过去分词，主语为单数第三人称be动词用is，sweep的过去分词为swept，故本题空格处填is swept。4. 本题的含义为杰克如此的小以至于他不懂这个问题，也就是说杰克明白这个问题还不够大，enough表示足够的含义，enough to do表示足以做某事，故本题空格处填enough to。5. 本题的主语为过去时，从句也用过去时，be的过去式为was，宾语从句为陈述句通常可以加一个关系词that。故本题空格处填that was。

对的，就是这个意思
