questions about quora data split

Hi, thanks for your excellent work!
Your split for quora data is used for so many succeed works, and now I want to use it. But I find the pairID in your data is not all matched to raw data successfuly. Here are many examples:

id: 184949 raw left: Which is the best phone under 15K in India? raw right: Which is the best mobile phone under 15K in India? your q1: How is the furniture industry ? your q2: What is the furniture industry like ?
id: 85926 raw left: How I can enhance my English language? raw right: How can I increase my English fluency? your q1: Why is the Economist banned in China ? your q2: Why is Economist banned in China ?

id: 131673 raw left: I am in Std 10th, scored really bad in SA1 . the marks in 5 subjects are (out of 90) 75,69,72,83,55.is there any chance of scoring 10 CGPA now? raw right: I scored really bad marks in 10th (CBSE) Term 1. Is there any chance of performing well by scoring well in term 2? your q1: By what peaceful , legal scenarios could Trump be removed from office ? your q2: Can Trump be impeded from taking office ?
