I need some foreign friends to complete a questionnaire for us. 

Its instruction goes as follows:

Read each paragraph carefully before you judge whether the two sentences are coherent or not by choosing ONE of the five items.（√）If the context is not suitable, please correct it, or write one instead.

I hope it won't take you much time. And your contribution to the scientific development will be much appreciated. Please contact with me when you are willing to help. My wechat account is :CarolineGu01, Skype account is :frier 15. OR if it is not accessible for you , you can leave you e-mail or other ways .I will contact with you soon.

Thanks again.

Caroline.
