Ans: Article Five
Ques: Article Five of the United States Constitution describes the process whereby the Constitution, the nation's frame of government, may be altered. Altering the Constitution consists of proposing an amendment or amendments and subsequent ratification. Amendments may be proposed either by the Congress with a two-thirds vote in both the House of Representatives and the Senate or by a convention of states called for by two-thirds of the state legislatures. To become part of the Constitution, an amendment must be ratified by either -- as determined by Congress -- the legislatures of three-quarters of the states or state ratifying conventions in three-quarters of the states. The vote of each state (to either ratify or reject a proposed amendment) carries equal weight, regardless of a state's population or length of time in the Union.

Answer this question: which article of the constitution allows changes to be made?
CoT: This is the relevant information: Article Five of the United States Constitution describes the process whereby the Constitution, the nation's frame of government, may be altered.

Ans: 1983
Ques: The first robot to assist in surgery was the Arthrobot, which was developed and used for the first time in Vancouver in 1983. Intimately involved were biomedical engineer, Dr. James McEwen, Geof Auchinleck, a UBC engineering physics grad, and Dr. Brian Day as well as a team of engineering students. The robot was used in an orthopaedic surgical procedure on 12 March 1984, at the UBC Hospital in Vancouver. Over 60 arthroscopic surgical procedures were performed in the first 12 months, and a 1985 National Geographic video on industrial robots, The Robotics Revolution, featured the device. Other related robotic devices developed at the same time included a surgical scrub nurse robot, which handed operative instruments on voice command, and a medical laboratory robotic arm. A YouTube video entitled Arthrobot illustrates some of these in operation.

When was the first robot used in surgery?
CoT: The relevant information to answer the above question is: The first robot to assist in surgery was the Arthrobot, which was developed and used for the first time in Vancouver in 1983.

Ans: roughly 4 to 60 C ( 39 to 140 F )
Ques: Context: The temperature range in which food-borne bacteria can grow is known as the danger zone. Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly 4 to 60 C (39 to 140 F). The FSIS stipulates that potentially hazardous food should not be stored at temperatures in this range in order to prevent foodborne illness (for example, a refrigerator's temperature must be kept below 4 C ( 40 F) ), and that food that remains in this zone for more than two hours should not be consumed. Foodborne microorganisms grow much faster in the middle of the zone, at temperatures between 21 and 47 C (70 and 117 F).

Question: what is the temperature of food danger zone?
CoT: The relevant sentence in the passage is: Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly 4 to 60 C (39 to 140 F).

Ans: Watson - Crick base pairs ( guanine - cytosine and adenine - uracil ) permit the formation of short double - stranded helices , and a wide variety of non-Watson - Crick interactions ( e.g. , G-U or A-A ) allow RNAs to fold into a vast range of specific three - dimensional structures
Ques: Intramolecular base pairs can occur within single-stranded nucleic acids. This is particularly important in RNA molecules (e.g., transfer RNA), where Watson-Crick base pairs (guanine-cytosine and adenine-uracil) permit the formation of short double-stranded helices, and a wide variety of non-Watson-Crick interactions (e.g., G-U or A-A) allow RNAs to fold into a vast range of specific three-dimensional structures. In addition, base-pairing between transfer RNA (tRNA) and messenger RNA (mRNA) forms the basis for the molecular recognition events that result in the nucleotide sequence of mRNA becoming translated into the amino acid sequence of proteins via the genetic code.

Answer this question: what are the base pair rules for rna?
CoT: The relevant information is: This is particularly important in RNA molecules (e.g., transfer RNA), where Watson-Crick base pairs (guanine-cytosine and adenine-uracil) permit the formation of short double-stranded helices, and a wide variety of non-Watson-Crick interactions (e.g., G-U or A-A) allow RNAs to fold into a vast range of specific three-dimensional structures.
