Article: PERTH--Search crews will send a submarine deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said. Angus Houst on said the crew on board the Ocean Shield will send the underwater vehicle sometime Monday evening. The Bluefin 21 submarine can create a sonar map of the area to chartany wreckage on the seafloor. The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes. "We haven't had a single detection in six days, and l guess it's time to go under water," said Houston. "Analysis of the four signals has reduced the search area on the ocean floor. The experts have therefore determined that the Australian Defense Vessel Ocean Shield will stop searching with the Towed Pinger Locator later today and use the underwater vehicle Bluefin 21 as soon as possible," he said at a news conference in Perth. _ He said the submarine will take 24 hours to do each task, including two hours to dive, 16 hours to search the bottom, then two more hours hack up and four hours to download data. Recovering the plane's flight data and cockpit voice recorders is necessary For investigators to try to figure out what happened to Flight 370, which disappeared on March 8. Houston said the search using the submarine will be a slaw and painstaking process. The submarine takes six times longer to cover the same area as the pinger locator,and will need about six weeks to two months to examine the present underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the submarine can dive. Question: According to the passage, the submarine _ . Options: A: will download data of the black boxes B: can find the aircraft wreckage within 24 hours C: will recover the plane's flight data and voice recorder D: can dive to a depth of no more than 4,500 meters

Read the article and select the best answer. Article: Visiting Balboa Island, in sunny southern California, proved an exciting experience that I will never forget. I had never been to Balboa Island, even though it is only about an hour from my home in northern San Diego. Our first stop was for a specialty called a "Balboa Bar". It is a famous chocolate covered ice cream on a stick, created many years ago. As we drove along the streets toward the boat, I also saw some interesting buildings that stood for many years. Many of the building designs seemed like dollhouses and someone in our group said that the style was called, Victorian. After we parked our car on one of the streets, we got on the boat sailing to Balboa Peninsula. As I looked around the boat, I saw a bird flying very close to the water and our boat. A little girl near the boat' s edge jumped out to touch it and shockingly fell into the water! Her dad, who stood nearby, jumped in after her at once and everyone on the boat ran to help. The boat's engine stopped and both father and daughter got saved with the help of people on the boat. On Balboa Peninsula my family and I went to various shops, especially for food! We saw a restaurant at the very end. We enjoyed our lunch there, at the first Ruby's Diner ever opened in southern California. Although I have been to other restaurants of this popular chain , being at the very first is a great memory. On our way back to Balboa island we stopped at the huge Ferris Wheel, bought some sugars and played games. It was an exciting afternoon walking around on Balboa Island. I look forward to returning soon to spend some time on the beach again or maybe even to try fishing! Question: "Balboa Bar" is the name of Options: A: a street B: a restaurant C: a food D: a building
