Example Input: The spin-off movie focuses on Matt Stifler (Tad Hilgenbrinck), the younger brother of Steve Stifler from the previous American Pie films. Matt is eager to enter the family business of making porno films, so he can prove to his older brother that he is "up to the standards of the Stifmeister." Stifler and his friends play a prank on the band students during the seniors' graduation ceremony by spraying pepper spray on the mouthpieces of the band's instruments. Matt narrowly escapes getting caught and stows the can of pepper spray in his front pocket, which subsequently leaks onto his genitals. The band members begin to play "Pomp and Circumstance", only to become too irritated by the pepper spray to continue. During the commotion, one of the students trips and pulls down the back curtain, which reveals Matt, who is washing his pepper-spray-soaked genitals in a drinking fountain, in front of the whole school.The band leader Elyse Houston (Arielle Kebbel) demands that Stifler be punished for ruining their performance, stating that he always gets away with his pranks because he is the school's star football player. The school's guidance counselor Chuck Sherman ("The Sherminator") (played by Chris Owen from the original American Pie films) decides that a worthwhile punishment would be for Stifler to attend band camp, in the hopes that he would make friends with the "bandies" and not follow in the footsteps of his much-hated brother.When first arriving, Matt is very disrespectful to the rules and also everyone at Tall Oaks and gets his band group in trouble. He is sent to the office of Noah Levenstein (Jim's father) (Eugene Levy), who works as the camp MACRO (Morale and Conflict Resolution Officer; he's filling in for Michelle as she is now pregnant), recommends that he try to fit in and earn the band's trust, which is the last thing that Matt wants to do. However, a phone call from a friend, who says that earning their trust will get him better footage for his video, inspires Matt to be much more respectful and humble towards the band.Matt finds out that his dorky roommate Ernie Kapolwitz (Jason Earles) has an extensive knowledge of spy cameras and technology, so Matt agrees to let him help with the filming, making his first friend at Tall Oaks. As Matt "is earning the band's trust" he gets into a big confrontation with their rival band leader, Brandon Van der Camp (Matt Barr), and even goes as far as to accept a duel challenge made by him, having no idea what a "duel" is.It turns out that a duel is the two performers showing off their music skills, with Brandon playing the snare drum, and Matt playing the triangle. Throughout the majority of the competition it seems that Brandon is the heavy favourite; during Brandon's second round of performing, Matt walks away humiliated. As Brandon is about to be declared the official winner, Matt comes back playing the bagpipes to the tune of 'Play That Funky Music' showing that he is actually a decent player, surprising everyone, including Elyse, who is pleasantly surprised by Matt's performance.As Matt is still recording the various happenings at the camp, he gradually becomes friends with some of the band members from his school. He gains some respect from Ernie after Matt sets him up on a date with tattooed bandmate Chloe (Crystle Lightning). Matt starts falling for Elyse, who is revealed to have been a friend of Matt's in 8th grade but had a falling out after Matt started hanging around with Steve and his friends and acting like The Stifmeister. Matt is eventually caught with his movies, and his once-friends want nothing more to do with him.After another talk with Jim's Dad, Matt comes to realize that his brother is not as great or cool as he once thought and that following in his footsteps is not a good idea, so he deletes all the videos he recorded at band camp. He even enlists the help of the band to help Elyse get the band scholarship that Stifler
Example Output: Who is the younger brother of Steve Stifler?

Example Input: Compelling evidence indicates that the CRISPR-Cas system protects prokaryotes from viruses and other potential genome invaders. This adaptive prokaryotic immune system arises from the clustered regularly interspaced short palindromic repeats (CRISPRs) found in prokaryotic genomes, which harbor short invader-derived sequences, and the CRISPR-associated (Cas) protein-coding genes. Here, we have identified a CRISPR-Cas effector complex that is comprised of small invader-targeting RNAs from the CRISPR loci (termed prokaryotic silencing (psi)RNAs) and the RAMP module (or Cmr) Cas proteins. The psiRNA-Cmr protein complexes cleave complementary target RNAs at a fixed distance from the 3' end of the integral psiRNAs. In Pyrococcus furiosus, psiRNAs occur in two size forms that share a common 5' sequence tag but have distinct 3' ends that direct cleavage of a given target RNA at two distinct sites. Our results indicate that prokaryotes possess a unique RNA silencing system that functions by homology-dependent cleavage of invader RNAs.
Example Output:
Gene silencing can be achieved by RNA interference (RNAi) in eukaryotic organisms. What is the name of the analogous process in prokaryotic organisms?
