(CNN) -- CNN Pentagon Correspondent Barbara Starr reported Thursday that the U.S. intelligence community has information that Russian artillery is firing into eastern Ukraine. The artillery pieces shown in the released footage are Russian M-46 130mm field guns with a range of a little over 16 miles. Why would the Russians do this? Simple -- this fits into their plan to support pro-Russian separatists in eastern Ukraine. The end game? I believe it is the eventual absorption of that region into the Russian Federation. The area in red on the map is where much of the fighting between the Ukrainian government and the pro-Russian rebels has been occurring over the last month. The separatists have downed several Ukrainian military aircraft in this area as the fighting raged. It is also the area in which Malaysia Airlines Flight 17 was shot down in what most of us believe was a tragic case of mistaken identity and inept use of modern weaponry.U.S. intelligence officials say they believe Russian artillery is firing into eastern UkraineRick Francona says the artillery firing is a significant escalation by the RussiansHe says Vladimir Putin's concern is to protect the pro-Russian rebelsFrancona: Ultimately, Putin may claim territory in eastern Ukraine to 'protect' rebels

(CNN) For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come. Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence -- which enables computers to "learn" -- looked at archival data obtained by NASA's planet-hunting Kepler telescope and uncovered the eighth planet. With the idea of eventually differentiating among exoplanets, Christopher Shallue, senior software engineer at Google AI in California, and Andrew Vanderburg, astronomer and NASA Sagan postdoctoral fellow at the University of Texas, Austin, trained a computer how to differentiate between images of cats and dogs.For the first time, eight planets have been found orbiting Kepler-90It is tied with our solar system for a star hosting the most known planets

(CNN) On a hot and sticky summer day in Manhattan, Nicole Levin was leaving a dentist appointment when it happened. The 41-year-old New Yorker exited a subway train, walked up a flight of concrete stairs to the bustling city street, and suddenly felt her tongue and throat swell. She started to sweat. She felt nauseous, short of breath and couldn't swallow. If Levin let any more time pass, she knew she wouldn't be able to breathe. She frantically opened her purse, wrapped her fingers around an EpiPen, and jammed it into her thigh beneath her workout pants. Immediately, she felt her throat open. She took in a deep breath of air -- a sigh of relief.The soaring cost of EpiPens has left many consumers with sticker shockAmericans are spending about 20% more on prescription drugs than in 2013, experts say 
 Questions:In other words, _ are not the only prescription drugs with steep price hikes. (A) Manhattan (B) Nicole Levin (C) New Yorker (D) Levin (E) EpiPen (F) Americans
