Alexander fled Macedon with his mother, dropping her off with her brother, King Alexander I of Epirus in Dodona, capital of the Molossians. He continued to Illyria, where he sought refuge with the Illyrian King and was treated as a guest, despite having defeated them in battle a few years before. However, it appears Philip never intended to disown his politically and militarily trained son. Accordingly, Alexander returned to Macedon after six months due to the efforts of a family friend, Demaratus, who mediated between the two parties. In the following year, the Persian satrap (governor) of Caria, Pixodarus, offered his eldest daughter to Alexander's half-brother, Philip Arrhidaeus. Olympias and several of Alexander's friends suggested this showed Philip intended to make Arrhidaeus his heir. Alexander reacted by sending an actor, Thessalus of Corinth, to tell Pixodarus that he should not offer his daughter's hand to an illegitimate son, but instead to Alexander. When Philip heard of this, he stopped the negotiations and scolded Alexander for wishing to marry the daughter of a Carian, explaining that he wanted a better bride for him. Philip exiled four of Alexander's friends, Harpalus, Nearchus, Ptolemy and Erigyius, and had the Corinthians bring Thessalus to him in chains. <sep>What was Alexander's relationship with the Illyrian King?<sep>They were brothers

On December 4, as news came in about the discoveries in Jordan, National Security Council (NSC) Counterterrorism Coordinator Richard Clarke wrote Berger, "If George's [Tenet's] story about a planned series of UBL attacks at the Millennium is true, we will need to make some decisions NOW." He told us he held several conversations with President Clinton during the crisis. He suggested threatening reprisals against the Taliban in Afghanistan in the event of any attacks on U.S. interests, anywhere, by Bin Laden. He further proposed to Berger that a strike be made during the last week of 1999 against al Qaeda camps in Afghanistan-a proposal not adopted. Warned by the CIA that the disrupted Jordanian plot was probably part of a larger series of attacks intended for the millennium, some possibly involving chemical weapons, the Principals Committee met on the night of December 8 and decided to task Clarke's Counterterrorism Security Group (CSG) to develop plans to deter and disrupt al Qaeda plots. Michael Sheehan, the State Department member of the CSG, communicated warnings to the Taliban that they would be held responsible for future al Qaeda attacks." Mike was not diplomatic," Clarke reported to Berger. With virtually no evidence of a Taliban response, a new approach was made to Pakistan. 13 General Anthony Zinni, the commander of Central Command (CENTCOM), was designated as the President's special envoy and sent to ask General Musharraf to "take whatever action you deem necessary to resolve the Bin Laden problem at the earliest possible time." But Zinni came back emptyhanded. As Ambassador William Milam reported from Islamabad, Musharraf was "unwilling to take the political heat at home." The CIA worked hard with foreign security services to detain or at least keep an eye on suspected Bin Laden associates. Tenet spoke to 20 of his foreign counterparts. Disruption and arrest operations were mounted against terrorists in eight countries. In mid-December, President Clinton signed a Memorandum of Notification (MON) giving the CIA broader authority to use foreign proxies to detain Bin Laden lieutenants, without having to transfer them to U.S. custody. The authority was to capture, not kill, though lethal force might be used if necessary.16Tenet would later send a message to all CIA personnel overseas, saying, "The threat could not be more real. <sep>When do the events in the whole article take place?<sep>Late 1999

Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen. <sep>What two things can happen to living organisms when the environment changes?<sep>They can progress or be taken captive
