Input: Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar.
"What are ways of transferring pollen?" is "Direct contact"?

Input: How can you describe your location? You might use a familiar system. You might say, 'I live at 1234 Main Street, Springfield, Ohio.' You could also say, 'I live right behind the Elementary School.' This method uses the school as a point of reference. Another example is, I am at the corner of Maple Street and Main Street. Both streets may be a good reference for anyone living in your town. Scientists must be able to pinpoint a feature they are studying. Scientists use a special system to describe locations. They use latitude and longitude as a reference. Lines of latitude and longitude form a grid. You may have used a grid system while doing graphing. This grid is centered on a reference point. Zero latitude is the equator. Lines of latitude run east to west. They divide the Earth from North to South. Lines of longitude run from north to south. They divide the Earth from East to West. Zero longitude runs through Greenwich, England. You may have heard the term, Greenwich Mean Time, or GMT. The system of latitude and longitude works well for objects that do not move.

Does the response "By polar coordinates" correctly answer the question "What are some ways besides latitude and longitude in which people describe location?"?

OPTIONS:
- no
- yes

Output: no

Responding to a wave of public dismay over the first designs for rebuilding Lower Manhattan, Gov. George Pataki has sent word that it's time to go back to the drawing board. It is the right message, sent while it is still early enough to do something constructive about the disappointing quality of the work so far. The governor, like Mayor Michael Bloomberg, now seems committed to creating a better mix of uses for ground zero, and a 24-hour community in Manhattan's downtown. While rethinking the plans will delay the original rebuilding schedule slightly, it does not need to stall progress if the governor keeps the pressure on the Lower Manhattan Development Corp. and the Port Authority of New York and New Jersey. New York cannot afford to have a gaping hole that mocks the city and its process for rebuilding what was destroyed. Pataki openly questioned the Port Authority's requirement that any plan for the site replace all the office, hotel and retail square footage lost in the attack on Sept. 11. More than anything else, that specification limited the designs to the undistinguished options presented two weeks ago. Renegotiating that issue with the World Trade Center leaseholders should begin immediately. Opening the process to other designers, both here and internationally, will help separate this urban plan from the ordinary. The city also needs to begin openly discussing what happens underground, in particular with the transportation network. At this point, planners have focused on short-term repair of PATH and subway lines, with medium-range proposals being shopped in Washington that could untangle the disorganized web of subway lines downtown. Within the next few weeks the Lower Manhattan Development Corp. and the Port Authority should offer some bigger ideas about how to connect the downtown area better to the rest of the region. Lowering West Street alongside the World Trade Center site and building a park or esplanade on top is another option that has been popular with those reviewing the first six public proposals. But it would be expensive, and the governor, the mayor and their friends in Washington will have to look at long-range ways to pay the bill. Pataki's recent remarks are a sign that he understands how central the rebuilding of Lower Manhattan will be to his own political legacy. Now he needs to follow through with action, to keep demonstrating that his core concern is coming up with the best possible plan, not simply keeping the issue on hold until after this fall's election.

Question: "What was the gaping hole that mocked the city from?"

The next evening, she arrived with a stack of glistening stopboxes containing sushi, sashimi, oysters in their shells, and Terran vegetables fresh plucked from their hydroponic beds. Wondering about the reason for her extravagance, I asked how work had gone that day. "Emil came in. He's taking Dream's End." "Emil?" "You've no memory left, old one. Emil Malaquez." You did that to test my affections." "What?" "Calling him by his first name. I did that in a comedy once.'Nights with Karl and Groucho.' It was before your time." "The critics liked it." "I'm glad." A moment later: "That's not why I called him 'Emil'." "No. We lunched together. He's nice."

Question: "What makes the older speaker wonder about the female speaker's extravagance?"

Response: "Sashimi"

Problem: It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place.

Question: "What is a compass?"

Answer: "a magnet that shows north"
