Q: The strong prescription against ain't in standard English has led to many misconceptions, often expressed jocularly (or ironically), as ''ain't ain't a word'' or ''ain't ain't in the dictionary.'' Ain't is listed in most dictionaries, including the Oxford Dictionary of English and Merriam-Webster. However, Oxford states ''it does not form part of standard English and should never be used in formal or written contexts'', and Merriam-Webster states it is ''widely disapproved as non-standard and more common in the habitual speech of the less educated''.
Can we conclude that is the word ain't in the webster dictionary?

- no

Restriction enzymes are endonucleases from eubacteria and archaea that recognize a specific DNA sequence. The nucleotide sequence recognized for cleavage by a restriction enzyme is called the restriction site. Typically, a restriction site will be a palindromic sequence about four to six nucleotides long. Most restriction endonucleases cleave the DNA strand unevenly, leaving complementary single-stranded ends. These ends can reconnect through hybridization and are termed ''sticky ends''. Once paired, the phosphodiester bonds of the fragments can be joined by DNA ligase. There are hundreds of restriction endonucleases known, each attacking a different restriction site. The DNA fragments cleaved by the same endonuclease can be joined together regardless of the origin of the DNA. Such DNA is called recombinant DNA; DNA formed by the joining of genes into new combinations. Restriction endonucleases (restriction enzymes) are divided into three categories, Type I, Type II, and Type III, according to their mechanism of action. These enzymes are often used in genetic engineering to make recombinant DNA for introduction into bacterial, plant, or animal cells, as well as in synthetic biology.

Bond paper is a high quality durable writing paper similar to bank paper but having a weight greater than 50 g/m. The most common weights are 60 g/m (16 lb), 75 g/m (20 lb) and 90 g/m (24 lb). The name comes from its having originally been made for documents such as government bonds. It is now used for letterheads and other stationery and as paper for electronic printers. Widely employed for graphic work involving pencil, pen and felt-tip marker, bond paper can sometimes contain rag fibre pulp, which produces a stronger, though rougher, sheet of paper.

OPTIONS:
- no
- yes

is bond paper the same as printer paper?

A: yes
Problem: Text: By December 14, the storm had covered the island's Troodos mountain range with snow. Snowing had begun several days earlier, with snow reaching a peak thickness of 70 cm (28 inches) in Troodos. Four hundred customers lost electricity, and several villages, including Armenohori, Farmakas, Kampi, and Sina Oros, completely lost it for extended periods of time.

Question: has it ever snowed in the middle east?

IN: Is it true that does the supreme court have the power to declare a law unconstitutional?

Two landmark decisions by the U.S. Supreme Court served to confirm the inferred constitutional authority for judicial review in the United States: In 1796, Hylton v. United States was the first case decided by the Supreme Court involving a direct challenge to the constitutionality of an act of Congress, the Carriage Act of 1794 which imposed a ''carriage tax''. The Court engaged in the process of judicial review by examining the plaintiff's claim that the carriage tax was unconstitutional. After review, the Supreme Court decided the Carriage Act was constitutional. In 1803, Marbury v. Madison was the first Supreme Court case where the Court asserted its authority for judicial review to strike down a law as unconstitutional. At the end of his opinion in this decision, Chief Justice John Marshall maintained that the Supreme Court's responsibility to overturn unconstitutional legislation was a necessary consequence of their sworn oath of office to uphold the Constitution as instructed in Article Six of the Constitution.
