Q: Kentucky generally has a 70 mph speed limit on rural freeways as of 2007. The speed limit is reduced to 55 on multi-lane highways in some urban areas (I-71/75 south of Cincinnati, I-64, I-65, I-71 and I-264 in Louisville, U.S. 60 bypass in Owensboro), and KY 4 in Lexington. There are two 50 mph areas in Louisville. One approaching the Sherman Minton Bridge crossing the Ohio River into Indiana on I-64, and one approaching the Kennedy Bridge on I-65 towards Indiana. The Transportation Cabinet is now authorized to raise any multilane, divided rural highway up to 65 MPH based on speed and design studies. Anyone may request an increase by contacting their local Transportation Cabinet office and specifying the roadway to be raised. Two-lane, undivided highways are limited to 55 MPH. Points are not assessed for speeds less than 10 mph over the speed limit only on limited access highways, or for tickets received by Kentucky licensed drivers out of state.
Can we conclude that is there a speed limit on the ohio river?
A: yes

Q: The dorsal fin is small; its height averages about 28 centimetres (11 in), and usually ranges between 20 and 40 cm (7.9 and 15.7 in), though it can be as small as 8 cm (3.1 in) or as large as 70 cm (28 in). It is visible only briefly during the dive sequence. Located around three-quarters of the way along the length of the body, it varies in shape from one individual to another; some only have a barely perceptible lump, but others may have prominent and falcate (sickle-shaped) dorsals. When surfacing to breathe, the blue whale raises its shoulder and blowhole out of the water to a greater extent than other large whales, such as the fin or sei whales. Observers can use this trait to differentiate between species at sea. Some blue whales in the North Atlantic and North Pacific raise their tail fluke when diving. When breathing, the whale emits a vertical single-column spout, typically 9 metres (30 ft) high, but reaching up to 12 metres (39 ft). Its lung capacity is 5,000 litres (1,300 US gal). Blue whales have twin blowholes shielded by a large splashguard.
Can we conclude that does a blue whale have a dorsal fin?
A: yes

Q: A binary search tree is a rooted binary tree, whose internal nodes each store a key (and optionally, an associated value) and each have two distinguished sub-trees, commonly denoted left and right. The tree additionally satisfies the binary search property, which states that the key in each node must be greater than or equal to any key stored in the left sub-tree, and less than or equal to any key stored in the right sub-tree. The leaves (final nodes) of the tree contain no key and have no structure to distinguish them from one another.
Can we conclude that is a binary tree a binary search tree?
A: no

Q: Bernie Taupin wrote ''Daniel'' after reading an article in either Time or Newsweek about a Vietnam War veteran who had been wounded, and wanted to get away from the attention he was receiving when he went back home. The last verse in the original draft was cut from the final version, which has led to some speculation on the contents.
