I'm taking a test and have to guess the right answer to the question after the article. Article: Deep in the western Amazon rainforest, live butterflies that drink turtle tears. That sounds like a line straight out of a fantasy novel, but it's one hundred percent real life! It's an unusual  sight--a crowd of butterflies flying around the eyes of yellow-spotted river turtles, trying to get a little tear.s. The poor turtles try to avoid them, hut the butterflies insist drinking  their tears until they've had their fill. The butterflies are likely attracted to the turtles' tears because the liquid drops contain  salt, specifically sodium, an important mineral that is rare in the western Amazon rainforest, said Phil Torres, a scientist who does much of his research at the Tambopata Research Center in Peru and is associated with Rice Univtrsity. Turtles get plenty of sodium  through their largely carnivorous  diet.  Meat contains significant levels of the salt, Torres told LiveScience. But herbivores  butterflies sometimes .struggle to get this extra mineral source, he added. Torres explained the western Amazon rainforest is lower in sodium than many places on earth, because it t is over l,000 miles away from the Atlantic Ocean---a main source of salt. The region is also cut off from the mineral dirt blown towards the west from the Andes Mountains. Most of these windblown minerals are removed from the air by the rain before they have a chance to reach the western Amazon. In fact, the butterflies have other sources to get sodium besides turtles' tears, which include animal urine , muddy river banks, sweaty clothes and so on. People can't help wondering if the process is painful for turtles. Torres said it's not completely clear, but the teary effort probably has little effect on the turtles, other than perhaps making them more vulnerable to their enemies like big cats, since the butterflies can block out their vision. Question: The butterflies drink turtle tears to   _ Options: A: help the turtles get sodium B: get a mineral from turtle tears C: rid waste from the turtles' bodies D: take turtles to the best water source         .

I'm taking a test and have to guess the right answer to the question after the article. Article: "We don't necessarily believe that new advertising, which might make consumers feel better about the Coke brand or better about the ads themselves , will actually result in consumers consuming more of the product," Morgan Stanley's Bill Pecoriello wrote in a research note the days after the investor   meeting . But Coke is optimistic it can regain its old magic, and is banking on a new slogan: "Welcome to the Coke side of life." BREAK THROUGH HIT?  With PepsiCo about to surpass  Coke as the beverage king on Wall Street--Pepsi's market capitalization has  _ in recent years to $97.9 billion, putting it less than a billion dollars behind its rival--the heat is on Coke . It's set to launch a new marketing campaign in March, 2006. And having taken a quick look at Coke's investor presentation on Dec. 7 in New York, my sense is that Coke may be moving in the right direction . Given the continued shift by consumers away from soda--Coke's stronghold --and into alternative beverages like juice, tea, and water, Coke badly needs a breakthrough hit. And given that shift away from soda, some analyists wonder whether even the catchiest new ads will be enough to put the fizz back into Coke. SAME OLD, UPDATED?     The new flavors of PowerAde sports drink will probably enable Coke to continue stealing market share from PepsiCo's Gatorade brand. And Coke is getting a little more creative with packaging, including new, aluminum bottles of Coke that will be sold in nightclubs, and an 8.4-ounce "100 calorie" version of its flagship Coke that will appeal to women who want fewer calories and will like the fact that the small can will fit in their purse. I doubt whether other new products will be successful, including a new coffee-flavored soda called Coke-Cola Black that I tried. Think carbonated coffee. But I'm not sure if the product, which Coke is pitching as an afternoon pick-me-up for the 35-and-over set, is going to pull people away from their afternoon Frappucino fix. And my opinion is that Vault, an orange-flavored energy... Question: What is the best title of the passage ? Options: A: Troubles in Coke Company B: The Importance of New Advertisements C: Varieties of New Products D: The Relationship between Coke and Pepsi
