Problem: Mammal:

The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsidssometimes referred to as mammal-like reptilesbefore giving rise to the proto-mammals (Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of the non-avian dinosaurs 66 million years ago.

From which time period did birds and reptiles began to appear from?
---
A: Carboniferous period

Problem: Perhaps the biggest sustainability problem in Tucson, with its high desert climate, is potable water supply. The state manages all water in Arizona through its Arizona Department of Water Resources (ADWR). The primary consumer of water is Agriculture (including golf courses), which consumes about 69% of all water. Municipal (which includes residential use) accounts for about 25% of use. Energy consumption and availability is another sustainability issue. However, with over 300 days of full sun a year, Tucson has demonstrated its potential to be an ideal solar energy producer.
How much of Tucson's water is used on residential/city use?

Answer: 25%

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Seminole Indians based in East Florida began raiding Georgia settlements, and offering havens for runaway slaves. The United States Army led increasingly frequent incursions into Spanish territory, including the 18171818 campaign against the Seminole Indians by Andrew Jackson that became known as the First Seminole War. The United States now effectively controlled East Florida. Control was necessary according to Secretary of State John Quincy Adams because Florida had become "a derelict open to the occupancy of every enemy, civilized or savage, of the United States, and serving no other earthly purpose than as a post of annoyance to them.".
What Indians lived in North Florida?
A: unanswerable

Question: In India, the British retained the Northern Circars, but returned all the French trading ports. The treaty, however, required that the fortifications of these settlements be destroyed and never rebuilt, while only minimal garrisons could be maintained there, thus rendering them worthless as military bases. Combined with the loss of France's ally in Bengal and the defection of Hyderabad to the British as a result of the war, this effectively brought French power in India to an end, making way for British hegemony and eventual control of the subcontinent.
Is there an answer to this question: What did France retain in India?

Answer: returned all the French trading ports

QUES: At present, plans are being considered for building a new dual carriageway west of Strasbourg, which would reduce the buildup of traffic in that area by picking up north and southbound vehicles and getting rid of the buildup outside Strasbourg. The line plans to link up the interchange of Hrdt to the north of Strasbourg, with Innenheim in the southwest. The opening is envisaged at the end of 2011, with an average usage of 41,000 vehicles a day. Estimates of the French Works Commissioner however, raised some doubts over the interest of such a project, since it would pick up only about 10% of the traffic of the A35 at Strasbourg. Paradoxically, this reversed the situation of the 1950s. At that time, the French trunk road left of the Rhine not been built, so that traffic would cross into Germany to use the Karlsruhe-Basel Autobahn.

The dual carriageway would link what interchange to the left of the Rhine?
