Background: Cassandra Nova is a fictional supervillain appearing in American comic books published by Marvel Comics, most commonly in association with the X-Men. Created by writer Grant Morrison and artist Frank Quitely, Cassandra first appeared in New X-Men #114 (July 2001). Cassandra is a "mummudrai," a parasitic life form born bodiless on the astral plane. The mummudrai that became Cassandra became telepathically entangled with the future Charles Xavier, who possesses vast mutant telepathic powers.
Context: On Earth-TRN342, Cassandra Nova has somehow survived for four thousand years and nearly conquered the world as the Great White Owl after she unleashed the Great Corruption and dropped entirely the Veil that separated the Main Reality with the reality of the Revenants, better known as the Mummundrai. As the Revenants were unleashed on Earth, Cassandra becomes their Queen and soon enough Bishop's presence in this reality came to Cassandra's attention. Bishop had been flung into this future Earth after failing in his attempt to kill Hope Summers and soon became a Revenant Hunter, even adopting a little girl named Amber. While on a mission to track a Bull Revenant called the Demon Bear for two months, Bishop and Amber found it in the forests outside a human settlement. Little did they realize that the Demon Bear was part of a trap set by the Great White Owl herself. Bear and Owl attacked, and Bishop held them off long enough for Amber to flee to safety, but ended up being possessed by both Revenants for his heroism. The Revenant Queen intended to use Bishop as a vessel, for she wanted to travel back in time to set off the Great Corruption several thousand years earlier than it originally happened. Re-materializing in the present outside Union Station in Los Angeles, California, the Owl Queen directed Bishop's body towards finding a worthy psychic to sacrifice for the Corruption's rituals. She zeroed in on a new mutant named Ginny Guzman, but the girl was already being fought over by Spiral and a team from the Jean Grey School. The Revenant Queen allowed the Demon Bear to run roughshod over the girl's defenders until she got close enough to project her own corrupted psyche into the child. She left behind a very rattled and confused Bishop and Demon Bear, who were knocked cold by Puck. Eventually Cassandra took possession over the body of Ginny and killed another new mutant psychic to begin the Great Corruption. As the Revenants began to be unleashed by the hundreds throughout Los Angeles, Bishop and his allies attacked the Owl Queen at her base at the Griffin Observatory and, through a complicated sequence of events, trapped Cassandra in the humanized body of Psylocke's Revenant counterpart, and then sacrificed her in a ritual that reversed the Great Corruption before it fully dropped the Veil to the Underworld.
Question: did Cassandra take over any other person or animal?
Answer: As the Revenants were unleashed on Earth, Cassandra becomes their Queen

Problem: Background: Andreas Nikolaus "Niki" Lauda (born 22 February 1949) is an Austrian former Formula One driver and a three-time F1 World Drivers' Champion, winning in 1975, 1977 and 1984. He is currently the only driver to have been champion for both Ferrari and McLaren, the sport's two most successful constructors. He is considered by some as one of the greatest F1 drivers of all time. More recently an aviation entrepreneur, he has founded and run two airlines (Lauda Air and Niki).
Context: After an unsuccessful start to the 1970s culminating in a disastrous start to the 1973 season, Ferrari regrouped completely under Luca di Montezemolo and were resurgent in 1974. The team's faith in the little-known Lauda was quickly rewarded by a second-place finish in his debut race for the team, the season-opening Argentine Grand Prix. His first Grand Prix (GP) victory - and the first for Ferrari since 1972 - followed only three races later in the Spanish Grand Prix. Although Lauda became the season's pacesetter, achieving six consecutive pole positions, a mixture of inexperience and mechanical unreliability meant Lauda won only one more race that year, the Dutch GP. He finished fourth in the Drivers' Championship and demonstrated immense commitment to testing and improving the car. The 1975 F1 season started slowly for Lauda; after no better than a fifth-place finish in the first four races, he won four of the next five driving the new Ferrari 312T. His first World Championship was confirmed with a third-place finish at the Italian Grand Prix at Monza; Lauda's teammate Regazzoni won the race and Ferrari clinched their first Constructors' Championship in 11 years; Lauda then picked up a fifth win at the last race of the year, the United States GP at Watkins Glen. He also became the first driver to lap the Nurburgring Nordschleife in under seven minutes, which was considered a huge feat as the Nordschleife section of the Nurburgring was two miles longer than it is today. Lauda famously gave away any trophies he won to his local garage in exchange for his car to be washed and serviced. Unlike 1975 and despite tensions between Lauda and Montezemolo's successor, Daniele Audetto, Lauda dominated the start of the 1976 F1 season, winning four of the first six races and finishing second in the other two. By the time of his fifth win of the year at the British GP, he had more than double the points of his closest challengers Jody Scheckter and James Hunt, and a second consecutive World Championship appeared a formality. It would be a feat not achieved since Jack Brabham's victories in 1959 and 1960. He also looked set to win the most races in a season, a record held by the late Jim Clark since 1963.
Question: who did he work with?
Answer:
Lauda's teammate Regazzoni
