　　parliamentarydevicethatslowsthesnail'spacethatprevailseveninthebestoftimesinthecongressionalsession

　　那个snail'space后面跟的that从句式修饰snail'space的?翻译起来感觉很怪啊

　　我的意思是snail'space后面这句thatprevailseveninthebestoftimesinthecongressionalsessionandtesttheenduranceofeveryoneassociatedwithit

　　是修饰snail'space的？
