Problem: Insect:

Insects are the only group of invertebrates to have developed flight. The evolution of insect wings has been a subject of debate. Some entomologists suggest that the wings are from paranotal lobes, or extensions from the insect's exoskeleton called the nota, called the paranotal theory. Other theories are based on a pleural origin. These theories include suggestions that wings originated from modified gills, spiracular flaps or as from an appendage of the epicoxa. The epicoxal theory suggests the insect wings are modified epicoxal exites, a modified appendage at the base of the legs or coxa. In the Carboniferous age, some of the Meganeura dragonflies had as much as a 50 cm (20 in) wide wingspan. The appearance of gigantic insects has been found to be consistent with high atmospheric oxygen. The respiratory system of insects constrains their size, however the high oxygen in the atmosphere allowed larger sizes. The largest flying insects today are much smaller and include several moth species such as the Atlas moth and the White Witch (Thysania agrippina).

Wings from the paranotal lobes are based on what theory?

A: paranotal theory

Context and question: Building first evolved out of the dynamics between needs (shelter, security, worship, etc.) and means (available building materials and attendant skills). As human cultures developed and knowledge began to be formalized through oral traditions and practices, building became a craft, and "architecture" is the name given to the most highly formalized and respected versions of that craft.
 What was building never considered?
Answer: unanswerable


Question: Pascal Lissouba, who became Congo's first elected president (1992–1997) during the period of multi-party democracy, attempted to implement economic reforms with IMF backing to liberalise the economy. In June 1996 the IMF approved a three-year SDR69.5m (US$100m) enhanced structural adjustment facility (ESAF) and was on the verge of announcing a renewed annual agreement when civil war broke out in Congo in mid-1997.
Is there an answer to this question: What does ESAF stand for?

Answer: enhanced structural adjustment facility


QUES: The MoD has been criticised for an ongoing fiasco, having spent £240m on eight Chinook HC3 helicopters which only started to enter service in 2010, years after they were ordered in 1995 and delivered in 2001. A National Audit Office report reveals that the helicopters have been stored in air conditioned hangars in Britain since their 2001[why?] delivery, while troops in Afghanistan have been forced to rely on helicopters which are flying with safety faults. By the time the Chinooks are airworthy, the total cost of the project could be as much as £500m.

When were the helicopters ordered?
