Problem: Text: Then, it was pointed out by Thomson and Searle that this electromagnetic mass also increases with velocity. This was further elaborated by Hendrik Lorentz (1899, 1904) in the framework of Lorentz ether theory. He defined mass as the ratio of force to acceleration, not as the ratio of momentum to velocity, so he needed to distinguish between the mass m L = 3 m (\displaystyle m_(L)=\gamma ^(3)m) parallel to the direction of motion and the mass m T = m (\displaystyle m_(T)=\gamma m) perpendicular to the direction of motion (where = 1 / 1 v 2 / c 2 (\displaystyle \gamma =1/(\sqrt (1-v^(2)/c^(2)))) is the Lorentz factor, v is the relative velocity between the aether and the object, and c is the speed of light). Only when the force is perpendicular to the velocity, Lorentz's mass is equal to what is now called ''relativistic mass''. Max Abraham (1902) called m L (\displaystyle m_(L)) longitudinal mass and m T (\displaystyle m_(T)) transverse mass (although Abraham used more complicated expressions than Lorentz's relativistic ones). So, according to Lorentz's theory no body can reach the speed of light because the mass becomes infinitely large at this velocity.

Question: does mass increase as you approach the speed of light?

OPTIONS:
- no
- yes
A: yes

Problem: Text: 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.

Question: can a dna polymerase initiate new strands of nucleic acid synthesis independently?

OPTIONS:
- no
- yes
A: no

Problem: Text: Because the courtroom workgroup deviates from the public consensus of how justice works, it has developed a deviant set of rules to continue its work and facilitate daily life for its participants. The academic theory of the courtroom workgroup has four cornerstone concepts that recognize this fact: Speed, Pragmatic Cynicism, Collegiality, and Secrecy. Efficient courtroom workgroups seek to process cases rather than dispense justice. This has been confirmed to greater and lesser extents in different courts. Defendants are assumed to be guilty. The procedural merits of the case are the true determinative factors of an outcome. Prosecutors and defense attorneys engage in a comparison of charges against possible procedural flaws and possible defenses to arrive at the going rate for a crime. These factors are used to determine how much punishment the plea bargain will offer. For example, group relationships and the desire to ''maintain'' a healthy working relationship are important to group members. The workings of the courtroom group and the ''going rate'' for given crimes are not matters for public disclosure. Estimates can be given to clients, but usually couched in terms of the prosecution's willingness to negotiate. (Summarized by O'Connor, T.R., 2005)

Question: the actors in the courtroom work group typically cooperate with one another?

OPTIONS:
- no
- yes
A:
yes
