Q: Question: How many years after the start of World War 1 did Drew lose his seat? Passage 1:John Michael Drew (17 October 1865 17 July 1947) was an Australian politician who served as a member of the Western Australian Legislative Council for 41 years in two separate terms between 1900 and his death in 1947. Born at Wanerenooka, Northampton, Western Australia, Drew established and edited several newspapers circulating in the Geraldton region before entering politics. A strong opponent of federation, he was elected to the Legislative Council in 1900. Nominally independent, Drew aligned himself with the Labor Party, and served in several Labor ministries during the early 1900s, in positions such as Minister for Agriculture, Minister for Lands, and Colonial Secretary. He officially joined the party in 1911, having been admitted to caucus sittings the previous year. During World War I, Drew supported conscription, but this issue, coupled with the ineffectual Scaddan Ministry, led to him losing his seat at the 1918 election. He regained his seat at the 1924 election, and subsequently served as chief secretary of the party, as well as Minister for Education, Health, and the North-West. Drew died of cancer in 1947, and was buried at Karrakatta Cemetery.
Passage 2:In June 1974, Guilfoyle was appointed to Billy Snedden's shadow ministry as the Coalition's spokesperson for the media. She supported Malcolm Fraser in the March 1975 leadership spill, and when he was successful she was moved to the higher-profile education portfolio. Following the dismissal of the Whitlam Government in November 1975, Guilfoyle was appointed Minister for Education in Fraser's caretaker ministry. This made her the first woman to hold a cabinet-level ministerial portfolio; is the first woman to be appointed to a Cabinet portfolio following her appointment as Minister for Education in the first Fraser government in 1975 she was the second woman appointed to cabinet, after Enid Lyons, and the second to be given a ministerial portfolio, after Annabelle Rankin. In December 1975, following the Coalition's victory at the 1975 election, Guilfoyle was appointed Minister for Social Security in the second Fraser Ministry. Her new portfolio was initially placed outside of cabinet, but she was reinstated in July 1976 after Ivor Greenwood's retirement. According to Fraser, she "contributed significantly to cabinet debates ... she could be totally relied on and she could think for herself she wasn't a captive to the bureaucracy".
Passage 3:Early confrontations between the Sasanian Empire of Shapur II with the nomadic hordes from Central Asia called the "Chionites" were described by Ammianus Marcellinus: he reports that in 356 CE, Shapur II was taking his winter quarters on his eastern borders, "repelling the hostilities of the bordering tribes" of the Chionites and the Euseni ("Euseni" is usually amended to "Cuseni", meaning the Kushans), finally making a treaty of alliance with the Chionites and the Gelani, "the most warlike and indefatigable of all tribes", in 358 CE. After concluding this alliance, the Chionites (probably of the Kidarites tribe) under their King Grumbates accompanied Shapur II in the war against the Romans, especially at the Siege of Amida in 359 CE. Victories of the Xionites during their campaigns in the Eastern Caspian lands were also witnesses and described by Ammianus Marcellinus.
