A gunman opened fire in Orlando's Pulse nightclub early morning Sunday , killing approximately 50 people and injuring another 53 . Clubbers were enjoying an evening at Pulse , which describes itself as " the hottest gay bar in Orlando , " when shots started to go off around 2 am. A hostage situation occurred , and didn't end until authorities used a vehicle armed to teeth to break down the door of the building and kill the gunman at around 5 am . Sunday morning's attack surpasses the shootings at Virginia Tech in 2007 and Sndy Hook Elementary School in 2012 to become the worst mass shooting in US history . Authorities have identified the shooter as 29-year-old Omar Saddiqui Mateen from Fort Pierce , about 120 miles southeast of Orlando . CNN reports Mr. Mateen was previously trained as a security guard . The federal government and FBI " have suggestions the individual has leanings towards Islamic terrorism , but right now we can't say definitely , " says Ron Hopper , assistant special agent of FBI's Orlando bureau . But Mateen's connection to Islamic terrorism has not been proven , leading authorities to also investigate the shooting as a possible hate crime against the LGBT community . The Orlando blood donation facility tweeted that the bank was in " urgent need " of donations Sunday morning following the shooting . But within hours , they announced their bank was at capacity due to the long lines of volunteers who showed up to donate . However , after the initial tweet at 10:40 Sunday morning , criticisms of the United States' stand on blood donation by the LGBT community resurfaced on social media from those who wanted to help but were prohibited due to their sexuality . " It's legal to buy an AR-15 assault rifle . It's illegal for a gay man to donate blood to victims of the massacre . The world makes no sense . " said John Barcus . ( LGBT : a community of four types of people ; lesbian , gay , bisexual , transgender .) According to the passage , the gunman   _   . A) had prejudice against the LGBT community B) had a close relationship with terrorist groups C) had some basic skills of fighting and shooting D) had planned the attack for a long time in advance

A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like boys and girls who live abroad with their parents, seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too. A man's mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our mind. Memory is the diary that we all carry about with us. The children who live abroad with their parents can learn two languages more easily, because   _  . A) they are very clever B) they have good teachers C) they have more chances to use these languages D) they have a better life

There comes a time in a person's life when they may realize that their laundry is just not coming out the way that they had hoped for. The whites may not be getting white enough or the color1s might be fading. This can cause you more money if you don't know how to properly do your laundry. These tips are lifesaving tips when it comes to washing your dirty clothes.     If you have a habit of throwing all your clothes into the washing machine together, you need to stop now. Washing your clothes in the same load will only cause them to fade onto each other or not become as clean as they could.     To save you lots of time, try buying a laundry sorter so that your clothes are already sorted and ready to be throne into the washing machine.     Another great advice would be to read the labels on the back of the clothing. The labels are there for a reason and this could help to save you a lot of money in the long run. It makes sense not to wash something in warm water when it specifically says to wash in cold water, if you did you could end up with a shrunken sweater.     There are basically five groups that your laundry should be sorted into; whites, lights, darks, bright color1ed clothes, and delicates.     The whites are basically anything white like your undergarments and t-shirts. Try not to get the whites and the lights confused.  The light color1ed clothes are those that can be white, striped, off-whites, pastels, cream color1ed, etc.     Dark clothes are those including blacks, blues, and browns. The reason that this is important is because dark clothes tend to fade onto other clothes and there are also special products like Woolite Dark that you can buy to keep them from fading. It just makes sense to wash these separately.     The bright clothes are those that are red, yellow, orange, green, florescent, etc. These clothes can make your other clothes turn color1s. The passage may be written by an experienced   _  . A) clothes maker B) money maker C) shopkeeper D) life coach
