PROBLEM: Passage: Dr. Frank Peralta is stabbed to death in his apartment one night. The detective on the case, Lt. Stevenson, quickly finds multiple witnesses putting Peralta's lover, Terry Collins, at the scene. However, when Stevenson finds Terry and questions her, she has an iron-clad alibi with multiple witnesses. It is revealed that Terry has an identical twin sister, Ruth, and the pair share the same job and routinely switch places for their own benefit. Stevenson and the district attorney are unable to prosecute, since the twins refuse to confirm which one of them has the alibi.
Unable to accept the "perfect crime", Lt. Stevenson asks Dr. Scott Elliot for help. Scott is an expert on twin study, and has been routinely encountering the Collins twins at their shared place of work, but does not know which one is which. As a front, Scott asks Terry and Ruth if he can study both of them individually as part of his research. The twins accept, though Ruth is worried that Scott might find out that Terry was at Peralta's apartment the night of the murder. However, Terry is attracted to Scott and insists that they can keep the secret for the sake of seeing him. She also comforts Ruth, reminding her that she was only at Peralta's apartment but didn't kill him.
From Scott's psychological tests and by spending time with them, he discovers that Ruth is kind and loving, while Terry is highly intelligent, insane, and has been manipulating Ruth almost their entire lives. Terry is jealous that people keep preferring Ruth over her, and is again enraged when Scott falls in love with Ruth instead of her. Terry starts methodically gaslighting Ruth, making her believe that she's hallucinating and going insane, in the hopes of pushing her to suicide. 
Question: What is the last name of the person whose murder the insane woman is suspected of committing?

SOLUTION: Peralta.

PROBLEM: Passage: Head girl Justine Fielding is escorted out of Fairview High School by the police, as other pupils look on.
Five days earlier, Justine is reading at the funeral of unpopular, asthmatic student Darren Mullet. She starts to talk about him, when Mullet's equally unpopular friend, Jason Banks (Olly Alexander), stands up in church and angrily calls her a hypocrite because she did not really know him. He is then thrown out by the sadistic P.E. teacher. Later on, Justine is talking to her friend Helena when school heart-throb Alex decides to invite her to a party that his popular friends, Bradley, Tasha, Khalillah, Sophie and Marcus are having. She decides to go.
At the party, when Justine arrives, Tasha tells Jez, the DJ, to say something about her appearance. He begins to rap about her in an unflattering manner. When Alex tells him to stop, he is literally thrown out of the party by Bradley. Later, Alex and Justine go to one of the bedrooms and kiss. Meanwhile, Bradley, Tasha, Khalillah, Marcus and Sophie all receive insulting and degrading text messages from Mullet's number. During this, someone puts on a clown costume and grabs a chainsaw, before heading up to Alex and Justine. It turns out to be Bradley, who is pranking them.
Jez goes to the cemetery and urinates on Mullet's grave. He is stabbed with a wooden crucifix by Mullet. 
Question: What is the name of the person who was stabbed with a wooden crucifix?

SOLUTION: Jez.

PROBLEM: Passage: Motivated by a variety of reasons from college tuition support, to a sense of purpose, best friends Dominic and Cole join the Army National Guard after graduating from their rural high school.  After persuading several of their friends to join them, the young men are sent to Afghanistan as part of the 107th Engineer Battalion, 168th Engineer Brigade, where they are tasked with searching for roadside bombs in order to keep roads safe for other troops.  By the time their deployment ends, they are no longer the carefree group of friends they were before enlisting; repeated bombs blasts around their convoys have led to TBI symptoms, and they have become increasingly disillusioned about their mission.
Coming home is no relief as they are now confronted with the silent war wounds of PTSD and TBI. The soldiers struggle with reintegration with society and some miss the simplicity in life they had while in Afghanistan. The latter half of the documentary focuses on their struggles on the home front and how each of them, and their families try to return to normal life. 
Question: Who is tasked with searching for roadside bombs?

SOLUTION:
Dominic.
