Question:
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.
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:
The Clark Sisters are an American gospel vocal group consisting of five sisters: Jacky Clark Chisholm (b. 1948), Denise Clark Bradford (b. 1953), Elbernita "Twinkie" Clark-Terrell (b. 1954), Dorinda Clark-Cole (b. 1957), and Karen Clark Sheard (b. 1960). The Clark Sisters are the daughters of gospel musician and choral director Mattie Moss Clark. They are credited for helping to bring gospel music to the mainstream and are considered as pioneers of contemporary gospel.
After a four-year gap between releases, the sisters continued as a foursome, signing with Rejoice Records, a division of Word. This new deal yielded the Grammy-nominated Heart & Soul (1986) featuring the mainstream single "Time Out". This project made a top 5 debut on Billboard's Gospel Charts and garnered the group a coveted Dove Award. It featured the original versions of "Jesus Is A Love Song", "Balm in Gilead", and "Pray for the USA", which has been re-recorded several times. The music took on a more contemporary sound with programmed drums and synthesizers. Also included on this album were "Smile, God Loves You", "Time Out", "I Am Blessed", and the funky "He'll Turn Your Scars Into Stars." In 1988, The Clark Sisters released their Billboard chart-topping and critically acclaimed album Conqueror. It featured a bolder, more intense sound, with synthesizers, drum machines and more funk-oriented beats. Conqueror quickly became a fan favorite with hits like "The Darkest Hour Is Just Before The Day" and the original studio version of "Jesus Forevermore". In 1989, The Clark Sisters released their highly anticipated live album, Bringing it Back Home, recorded in their home town of Detroit. It was the last recording from The Clark Sisters on Word Records' Rejoice imprint and the last group album with Twinkie just before the launch of her solo career. The album included both previous hits and new material. It featured guest appearances from gospel icon Rance Allen and backing choir vocals from The Michigan State Choir directed by Dr. Mattie Moss Clark. In 1994, the Clark Sisters released their last studio album before breaking grounds into their successful solo careers. Their last studio album of the decade, Miracle, was the first album The Clark Sisters recorded without the songwriting and vocals of Twinkie Clark. Produced by BeBe Winans & Michael J. Powell, this disc features a very pop version of the Clark Sisters classic "Expect A Miracle" (now titled "Miracle") and a remake of the classic "Jesus Is The Best Thing". Dorinda made her songwriting debut on a Clark Sisters recording with "Work To Do". That album, although it fared well in sales, did not match the success of previous albums due to the Clark Sisters not being able to tour and promote the project, due to the illness of their mother, Dr. Mattie Moss Clark, who died in September 1994 from diabetes complications.
