When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though.

These contradictory orders, and even letters of recall, reached Law on his march, but though he sent back M. Sinfray with letters to M. Bugros and Coja Wajid--which the latter afterwards made over to Clive--he continued his march to Patna, where he arrived on the 3rd of June, and was well received by Raja Ramnarain, and where he was within four or five days' march or sail from Sooty, the mouth of the Murshidabad or Cossimbazar river, and therefore in a position to join the Nawab whenever it might be necessary. In the mean time fate had avenged Law on one of his lesser enemies. This was that Ranjit Rai, who had insulted him during his interview with the Seths. The latter had pursued their old policy of inciting the English to make extravagant demands which they at the same time urged the Nawab to refuse. To justify one such demand, the English produced a letter in the handwriting of Ranjit Rai, purporting to be written at the dictation of the Seths under instructions from the Nawab. The latter denied the instructions, and the Seths promptly asserted that the whole letter was a forgery of their agent's.

Question: "Who wrote the letter?"

Response: "British People"

Problem: The Vice President stated that he called the President to discuss the rules of engagement for the CAP. He recalled feeling that it did no good to establish the CAP unless the pilots had instructions on whether they were authorized to shoot if the plane would not divert. He said the President signed off on that concept. The President said he remembered such a conversation, and that it reminded him of when he had been an interceptor pilot. The President emphasized to us that he had authorized the shootdown of hijacked aircraft. The Vice President's military aide told us he believed the Vice President spoke to the President just after entering the conference room, but he did not hear what they said. Rice, who entered the room shortly after the Vice President and sat next to him, remembered hearing him inform the President, "Sir, the CAPs are up. Sir, they're going to want to know what to do." Then she recalled hearing him say, "Yes sir." She believed this conversation occurred a few minutes, perhaps five, after they entered the conference room. We believe this call would have taken place sometime before 10:10 to 10:15. Among the sources that reflect other important events of that morning, there is no documentary evidence for this call, but the relevant sources are incomplete. Others nearby who were taking notes, such as the Vice President's chief of staff, Scooter Libby, who sat next to him, and Mrs. Cheney, did not note a call between the President and Vice President immediately after the Vice President entered the conference room. At 10:02, the communicators in the shelter began receiving reports from the Secret Service of an inbound aircraft-presumably hijacked-heading toward Washington. That aircraft was United 93. The Secret Service was getting this information directly from the FAA. The FAA may have been tracking the progress of United 93 on a display that showed its projected path to Washington, not its actual radar return. Thus, the Secret Service was relying on projections and was not aware the plane was already down in Pennsylvania.

(CNN) -- Cuba will pardon more than 2,900 prisoners, the government said Friday, though U.S. subcontractor Alan Gross is not among those who will be freed. The decision to release the prisoners follows "numerous requests" from their family members and religious institutions, and is a humanitarian gesture, said Cuban President Raul Castro. Among those who might be freed are prisoners over the age of 60, along with those who are sick, female or young with no previous criminal record. With some exceptions, prisoners convicted of spying, terrorism, murder and drug trafficking will not be released. Those who will be freed have already served a "important" part of their sentences and exhibited good behavior, according to an official statement published on the state-run website Cubadebate. The jailed American, Gross, will not be among those pardoned, the Cuban Interests Section in Washington said. Gross was jailed in December 2009, when he was working as a subcontractor on a U.S. Agency for International Development project aimed at spreading democracy. Castro has accused him of importing satellite equipment to connect dissidents to the Internet, and this year Cuba's highest court upheld the 15-year sentence imposed on Gross for committing crimes against the security of the state. He has maintained his innocence and said he was trying to help connect the Jewish community to the Internet. Castro, speaking to the National Assembly, said that 86 prisoners from 25 countries would be among those released in coming days. He cited the upcoming visit of Pope Benedict XVI as one of the motivations behind the move, which he said showed the "generosity and strength of the revolution." The pope has said he plans to visit Mexico and Cuba before Easter.

Question: "How many years of his sentence does Alan have left?"

OPTIONS:
- no
- yes

Answer: "Fifteen"

Response:
no
