Q: An unopened bottle of Coffee-Mate can last up to two years with no refrigeration and can stay fresh for two weeks once it is opened. The product is popular in offices where refrigeration may not be available. A benefit of the non-dairy creamer is that it is good for those individuals who are lactose-intolerant. Once opened, liquid non-dairy creamer should be refrigerated.
Can we conclude that do you have to refrigerate coffee mate creamer?
A: yes

Q: The flag of the United States is sometimes burned in protest of the policies of the American government, both within the country and abroad. The United States Supreme Court in Texas v. Johnson, 491 U.S. 397 (1989), and reaffirmed in U.S. v. Eichman, 496 U.S. 310 (1990), has ruled that due to the First Amendment to the United States Constitution, it is unconstitutional for a government (whether federal, state, or municipal) to prohibit the desecration of a flag, due to its status as ''symbolic speech.'' However, content-neutral restrictions may still be imposed to regulate the time, place, and manner of such expression. If the flag that was burned was someone else's property (as it was in the Johnson case, since Johnson had stolen the flag from a Texas bank's flagpole), the offender could be charged with petty larceny (a flag usually sells at retail for less than USD 20), or with destruction of private property, or possibly both.
Can we conclude that is it illegal to sign the american flag?
A: no

Q: Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring. Heteropaternal superfecundation refers to the fertilization of two separate ova by two different fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins. While heteropaternal superfecundation is referred to as a form of atypical twinning, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either separate occurrences of sexual intercourse or through artificial insemination.
Can we conclude that can a woman produce twins of different fathers?
A: no

Q: Carnitine (-hydroxy--N-trimethylaminobutyric acid, 3-hydroxy-4-N,N,N-trimethylaminobutyrate) is a quaternary ammonium compound involved in metabolism in most mammals, plants and some bacteria. Carnitine may exist in two isomers, labeled D-carnitine and L-carnitine, as they are optically active. At room temperature, pure carnitine is a white powder, and a water-soluble zwitterion with low toxicity. Carnitine only exists in animals as the L-enantiomer, and D-carnitine is toxic because it inhibits the activity of L-carnitine. Carnitine, derived from an amino acid, is found in nearly all organisms and animal tissue. Carnitine is the generic expression for a number of compounds that include L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine. It is most accumulated in cardiac and skeletal muscles as it accounts for 0.1% of its dry matter. It was first derived from meat extracts in 1905, therefore the name carnitine is derived from Latin ''carnus'' or flesh. The body synthesizes enough carnitine from lysine side chains to keep up with the needs of energy production in the body as carnitine acts as a transporter of long-chain fatty acids into the mitochondria to be oxidized and produce energy. Some individuals with genetic or medical disorders (like preterm infants) cannot make enough, so this makes carnitine a conditionally essential nutrient for them.
Can we conclude that is carnitine the same as l-carnitine?
A:
no
