Q: Extract the answer to the question from the following context. Question: The CDs are sometimes what that allows it to become defective? Context: CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.

Q: Extract the answer to the question from the following context. Question: What is the recipe for protein? Context: Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.
A: alleles

Q: Extract the answer to the question from the following context. Question: What type of match is a ladder match? Context: Many modern specialty matches have been devised, with unique winning conditions. The most common of these is the ladder match. In the basic ladder match, the wrestlers or teams of wrestlers must climb a ladder to obtain a prize that is hoisted above the ring. The key to winning this match is that the wrestler or team of wrestlers must try to incapacitate each other long enough for one wrestler to climb the ladder and secure that prize for their team. As a result, the ladder can be used as a weapon. The prizes include but are not limited to any given championship belt (the traditional prize), a document granting the winner the right to a future title shot, or any document that matters to the wrestlers involved in the match (such as one granting the winner a cash prize). Another common specialty match is known as the battle royal. In a battle royal, all the wrestlers enter the ring to the point that there are 20-30 wrestlers in the ring at one time. When the match begins, the simple objective is to throw the opponent over the top rope and out of the ring with both feet on the floor in order to eliminate that opponent. The last wrestler standing is declared the winner. A variant on this type of match is the WWE's Royal Rumble where two wrestlers enter the ring to start the match and other wrestlers follow in 90 second intervals (previously 2 minutes) until 30-40 wrestlers have entered the ring. All other rules stay the same. For more match types, see Professional wrestling match types.
