Example Input: 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>Who told Pixodarus that he should not offer his daughter's hand to an illegitimate son, but instead to Alexander?<sep>The illegitimate son

Example Input: He read the telegram again. In desperation he went back to the long distance booth, but found the line still out of order, and a wire had come giving the details of the damage done by the storm. It would be several days before communication could be established. There was no help coming from headquarters, and from the wording of the telegram there seemed to be a reason for their not giving clear details. He must get a copy of the paper. Reluctantly he went to the printing office and made known his errand. Mr. Driggs was delighted to give him the paper--he had it some place, though he very seldom opened any of his exchanges. He evidently bore Mr. Steadman no ill-will for his plain talk two weeks ago. With some difficulty he found it, with its wrapper still intact. It was a loose wrapper, which slipped off and on easily. Mr. Steadman remarked carelessly that there was an editorial in it to which his attention had been drawn, on hearing which Mr. Driggs turned his head and winked at an imaginary accomplice. <sep>What did Mr. Driggs still have intact around the item he was getting for Mr. Steadman?<sep>Box
Example Output: No
