PROBLEM: Passage: Much of the work of the Scottish Parliament is done in committee. The role of committees is stronger in the Scottish Parliament than in other parliamentary systems, partly as a means of strengthening the role of backbenchers in their scrutiny of the government and partly to compensate for the fact that there is no revising chamber. The principal role of committees in the Scottish Parliament is to take evidence from witnesses, conduct inquiries and scrutinise legislation. Committee meetings take place on Tuesday, Wednesday and Thursday morning when Parliament is sitting. Committees can also meet at other locations throughout Scotland. Question: Taking evidence from witnesses is one of committees' what?

PROBLEM: Passage: These chloroplasts, which can be traced back directly to a cyanobacterial ancestor, are known as primary plastids ('plastid' in this context means almost the same thing as chloroplast). All primary chloroplasts belong to one of three chloroplast lineages—the glaucophyte chloroplast lineage, the rhodophyte, or red algal chloroplast lineage, or the chloroplastidan, or green chloroplast lineage. The second two are the largest, and the green chloroplast lineage is the one that contains the land plants. Question: How many chloroplast lineages are there?

SOLUTION: three

PROBLEM: Passage: Child labour is common in Kenya. Most working children are active in agriculture. In 2006, UNICEF estimated that up to 30% of girls in the coastal areas of Malindi, Mombasa, Kilifi, and Diani were subject to prostitution. Most of the prostitutes in Kenya are aged 9–18. The Ministry of Gender and Child Affairs employed 400 child protection officers in 2009. The causes of child labour include poverty, the lack of access to education and weak government institutions. Kenya has ratified Convention No. 81 on labour inspection in industries and Convention No. 129 on labour inspection in agriculture. Question: What is the age range of most prostitutes in Kenya?

SOLUTION:
9–18
