Read the article and select the best answer. Article: Imagine living in a city made of glass. No, this isn't a fairy tale. If you could grab your diving gear and swim down 650 feet into the Pacific Ocean off the coast of Washington State, you would witness the secret world of glass reefs. The reef you'd be looking at is made up of glass sponges . But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old. When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms. Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges. "It's a new ecosystem we know nothing about," said Dr. Johnson. The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a "kindergarten" by scientists. Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home. The Washington coast isn't the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were to see it. Question: Which of the following is TRUE according to the passage? Options: A: The sponges must feel soft. B: Silica comes from animals' body fluid. C: Methane is harmful to glass sponges. D: Glass sponges depend on the bacteria for a living.

The truth is that millions of Americans lost their jobs, their homes and their life savings because of the greed and illegal behavior of Wall Street.Even Federal Reserve Chairman Ben Bemanke also said the protesters hold the view that the financial institutions are responsible for "getting the US into this mess", and added, "I can't blame those protesters." Where do we go from this movement? How do we calm the protesters' anger? For starters, we should break up the super financial institutions.Left to their own selfish will.Wall Street bankers will continue to gamble with other people's money.There also is a sound economic argument against too few owning far too much.The idea that six super financial institutions (Bank of America, CitiGroup, JP Morgan Chase, Wells Fargo, Morgan Stanley and Goldman Sachs) can take control over the economy frightens anyone who believes in a competitive free-market system.Good Republican presidents like William Howard Taft and Teddy Roosevelt broke up Standard Oil, the Railroad Trusts .and other huge companies a century ago. Real unemployment is more than 16%.Average family income has declined by $3,600 over the last decade.A record 46 million Americans live in poverty.The gap between the very rich and everyone else, the widest of any major country, is growing wider.Now is the time for us to end the financial oligarchy that has been so harmful to our economy.If a bank is too big, it is too big to exist. Question: Which of the following belongs to the super financial institutions? Options: A: Standard Oil B: Federal Reserve C: JP Morgan Chase D: Teddy Roosevelt
