TASK DEFINITION: You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").
PROBLEM: Paragraph- Sent 1: Alexander fled Macedon with his mother, dropping her off with her brother, King Alexander I of Epirus in Dodona, capital of the Molossians.
Sent 2: 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.
Sent 3: However, it appears Philip never intended to disown his politically and militarily trained son.
Sent 4: Accordingly, Alexander returned to Macedon after six months due to the efforts of a family friend, Demaratus, who mediated between the two parties.
Sent 5: In the following year, the Persian satrap (governor) of Caria, Pixodarus, offered his eldest daughter to Alexander's half-brother, Philip Arrhidaeus.
Sent 6: Olympias and several of Alexander's friends suggested this showed Philip intended to make Arrhidaeus his heir.
Sent 7: 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.
Sent 8: 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.
Sent 9: Philip exiled four of Alexander's friends, Harpalus, Nearchus, Ptolemy and Erigyius, and had the Corinthians bring Thessalus to him in chains.
Question: Who told Pixodarus that he should not offer his daughter's hand to an illegitimate son, but instead to Alexander?.

SOLUTION: 7, 8.

PROBLEM: Paragraph- Sent 1: Not until 1998 did al Qaeda undertake a major terrorist operation of its own, in large part because Bin Ladin lost his base in Sudan.
Sent 2: Ever since the Islamist regime came to power in Khartoum, the United States and other Western governments had pressed it to stop providing a haven for terrorist organizations.
Sent 3: Other governments in the region, such as those of Egypt, Syria, Jordan, and even Libya, which were targets of some of these groups, added their own pressure.
Sent 4: At the same time, the Sudanese regime began to change.
Sent 5: Though Turabi had been its inspirational leader, General Omar al Bashir, president since 1989, had never been entirely under his thumb.
Sent 6: Thus as outside pressures mounted, Bashir's supporters began to displace those of Turabi.
Sent 7: The attempted assassination in Ethiopia of Egyptian President Hosni Mubarak in June 1995 appears to have been a tipping point.
Sent 8: The would-be killers, who came from the Egyptian Islamic Group, had been sheltered in Sudan and helped by Bin Ladin.
Sent 9: When the Sudanese refused to hand over three individuals identified as involved in the assassination plot, the UN Security Council passed a resolution criticizing their inaction and eventually sanctioned Khartoum in April 1996.
Sent 10: A clear signal to Bin Ladin that his days in Sudan were numbered came when the government advised him that it intended to yield to Libya's demands to stop giving sanctuary to its enemies.
Sent 11: Bin Ladin had to tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave the country.
Sent 12: Outraged, several Libyan members of al Qaeda and the Islamic Army Shura renounced all connections with him.
Sent 13: Bin Ladin also began to have serious money problems.
Sent 14: International pressure on Sudan, together with strains in the world economy, hurt Sudan's currency.
Sent 15: Some of Bin Ladin's companies ran short of funds.
Sent 16: As Sudanese authorities became less obliging, normal costs of doing business increased.
Sent 17: Saudi pressures on the Bin Ladin family also probably took some toll.
Sent 18: In any case, Bin Ladin found it necessary both to cut back his spending and to control his outlays more closely.
Question: What was the assassination of President Hosni Mubarak a tipping point for?.

SOLUTION: 4, 5, 6, 7.

PROBLEM: Paragraph- Sent 1: The one person who, by his interference, could have settled all doubts was debarred by circumstances from interfering in the matter.
Sent 2: Wykham Delandre had quarrelled with his sister--or perhaps it was that she had quarrelled with him--and they were on terms not merely of armed neutrality but of bitter hatred.
Sent 3: The quarrel had been antecedent to Margaret going to Brent's Rock.
Sent 4: She and Wykham had almost come to blows.
Sent 5: There had certainly been threats on one side and on the other; and in the end Wykham, overcome with passion, had ordered his sister to leave his house.
Sent 6: She had risen straightway, and, without waiting to pack up even her own personal belongings, had walked out of the house.
Sent 7: On the threshold she had paused for a moment to hurl a bitter threat at Wykham that he would rue in shame and despair to the last hour of his life his act of that day.
Sent 8: Some weeks had since passed; and it was understood in the neighbourhood that Margaret had gone to London, when she suddenly appeared driving out with Geoffrey Brent, and the entire neighbourhood knew before nightfall that she had taken up her abode at the Rock.
Sent 9: It was no subject of surprise that Brent had come back unexpectedly, for such was his usual custom.
Sent 10: Even his own servants never knew when to expect him, for there was a private door, of which he alone had the key, by which he sometimes entered without anyone in the house being aware of his coming.
Sent 11: This was his usual method of appearing after a long absence.
Question: What is Brent's usual method of coming home after a long absence?.

SOLUTION:
9, 10, 11.
