Problem: The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.
What fraction of land was under cultivation using the two-field system?
The answer is the following: one half

Problem: Some Samoans are spiritual and religious, and have subtly adapted the dominant religion of Christianity to 'fit in' with fa'a Samoa and vice versa. As such, ancient beliefs continue to co-exist side-by-side with Christianity, particularly in regard to the traditional customs and rituals of fa'a Samoa. The Samoan culture is centred around the principle of vafealoa'i, the relationships between people. These relationships are based on respect, or fa'aaloalo. When Christianity was introduced in Samoa, most Samoan people converted. Currently 98% of the population identify themselves as Christian.
What percentage of Samoans call themselves Christians?
The answer is the following: 98%

Problem: The rising population has resulted in an increased demand on fish stocks, which are under stress; although the creation of the Funafuti Conservation Area has provided a fishing exclusion area to help sustain the fish population across the Funafuti lagoon. Population pressure on the resources of Funafuti and inadequate sanitation systems have resulted in pollution. The Waste Operations and Services Act of 2009 provides the legal framework for waste management and pollution control projects funded by the European Union directed at organic waste composting in eco-sanitation systems. The Environment Protection (Litter and Waste Control) Regulation 2013 is intended to improve the management of the importation of non-biodegradable materials. In Tuvalu plastic waste is a problem as much imported food and other commodities are supplied in plastic containers or packaging.
What organization has funded a waste management control plan on Tuvalu?
The answer is the following:
European Union
