Question 2
答案：D
关键词：purpose/S.K.I

定位原文：Street Business Partnerships部分第1点“The S.K.I. Bicycle Courier Service first started in the Sudan. Participants in this enterprise were supplied with bicycles, which they used to deliver parcels and messages, and which they were required to pay for gradually from their wages. A similar program was taken up in Bangalore, India.”
解题思路：提供courier service的两个国家分别是Sudan和India。

Question 11
答案：NO
关键词：loan
定位原文：Lessons learned部分第5点“Small loans are provided initially for …ranged from US$30-$100.”
