Why I post my questions to the forum but very often no one answer

Hello, I’m student from Taiwan ROC, I’ve graduated from university this semester and is going to pursue my graduate study in USA. This is the first time I prepare for the GMAT exam and sometimes I just think my English isn’t good enough since I’m non-native speaker, in Reading Comprehension/Critical Reasoning section I raised and posted lots of doubts to some questions, however I found that no one answer or even discussed with my question. I was wondering how it came to be this phenomenon, maybe other participants in Gmatclub to these specific questions thought that my questions are too foolish to answer because sometimes maybe my English-level is poor that I cannot grasp the meaning of each sentence or paragraph ,or that they just don’t know how to respond to my doubts….?

(recently I’ve tried to post some explanations to questions if I can manage it, but for some more tricky or difficult questions I cannot thus I will raise my doubts to these questions)
