Q: DNA polymerases are a family of enzymes that carry out all forms of DNA replication. DNA polymerases in general cannot initiate synthesis of new strands, but can only extend an existing DNA or RNA strand paired with a template strand. To begin synthesis, a short fragment of RNA, called a primer, must be created and paired with the template DNA strand.
Can we conclude that can a dna polymerase initiate new strands of nucleic acid synthesis independently?
A: no

Q: In English football, ''The Invincibles'' is a nickname that has been used to refer to the Preston North End team of the 1888--89 season, managed by William Sudell, and the Arsenal team of the 2003--04 season managed by Arsene Wenger. Preston North End earned the nickname after completing an entire season undefeated in league and cup competition (27 games), while Arsenal were undefeated in the league only (38 games). The actual nickname of the Preston team was the ''Old Invincibles'', but both versions have been in use.
Can we conclude that has a premier league team ever gone undefeated?
A: yes

Q: From 1976 to 1983, several states voluntarily raised their purchase ages to 19 (or, less commonly, 20 or 21), in part to combat drunk driving fatalities. In 1984, Congress passed the National Minimum Drinking Age Act, which required states to raise their ages for purchase and public possession to 21 by October 1986 or lose 10% of their federal highway funds. By mid-1988, all 50 states and the District of Columbia had raised their purchase ages to 21 (but not Puerto Rico, Guam, or the Virgin Islands, see Additional Notes below). South Dakota and Wyoming were the final two states to comply with the age 21 mandate. The current drinking age of 21 remains a point of contention among many Americans, because of it being higher than the age of majority (18 in most states) and higher than the drinking ages of most other countries. The National Minimum Drinking Age Act is also seen as a congressional sidestep of the tenth amendment. Although debates have not been highly publicized, a few states have proposed legislation to lower their drinking age, while Guam has raised its drinking age to 21 in July 2010.
Can we conclude that is there any state in the us where the drinking age is 18?
A:
no
