Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Question: "What species in this passage is mentioned to use use the Earths magnetic fields to guide its annual migration?"

OPTIONS:
- no
- yes

Answer: "Vulture"

Response: no

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.

(CNN) -- Declaring 2010 "The best year in safety performance in our company's history," Transocean Ltd., owner of the Gulf of Mexico oil rig that exploded, killing 11 workers, has awarded its top executives hefty bonuses and raises, according to a recent filing with the U.S. Securities and Exchange Commission. That includes a $200,000 salary increase for Transocean president and chief executive officer Steven L. Newman, whose base salary will increase from $900,000 to $1.1 million, according to the SEC report. Newman's bonus was $374,062, the report states. Newman also has a $5.4 million long-term compensation package the company awarded him upon his appointment as CEO in March 2010, according to the SEC filing. The latest cash awards are based in part on the company's "performance under safety," the Transocean filing states. "Notwithstanding the tragic loss of life in the Gulf of Mexico, we achieved an exemplary statistical safety record as measured by our total recordable incident rate and total potential severity rate," the SEC statement reads. "As measured by these standards, we recorded the best year in safety performance in our Company's history." The company called that record "a reflection on our commitment to achieving an incident-free environment, all the time, everywhere," the SEC filing states. The company did not respond to an e-mail from CNN seeking comment. The April 20, 2010, explosion on the Deepwater Horizon rig injured 17 workers and killed 11 others, including nine Transocean employees, according to the SEC filing. It has been called the worst spill in U.S. history. The well was capped three months later, but not before millions of barrels of oil spilled into the Gulf. In January, President Barack Obama's National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling released a report that spread blame for the accident among Transocean, BP -- which leased the rig -- and Halliburton, which installed the rig's cement casing.

Question: "Which company did not respond to CNN's email seeking comment?"

OPTIONS:
- no
- yes

Answer: "Halliburton"
