Q: Question: Which of the actresses who played Tina Mahon is older? Passage 1:Thesiger was educated at Eton College before attending the Royal Military College, Sandhurst for training as an infantry officer. Aged 22, Thesiger was Gazetted into the Rifle Brigade as a second lieutenant on 19 March 1890, and served with his unit in England until 1898, when the regiment was dispatched to Egypt. During his service in England he was promoted to lieutenant on 10 February 1892, and to captain on 26 July 1897. In Egypt, the Rifle Brigade served on the Nile expedition under Horatio Kitchener during the Mahdist War and was present at the Battle of Omdurman which decided the campaign. Thesiger received a brevet appointment as major on 16 November 1898 for his service.
Passage 2:The United States of America will compete at the 2015 World Championships in Athletics from August 22 to August 30 in Beijing, China. The membership of the team was selected at the 2015 USA Outdoor Track and Field Championships. However, membership on the team was subject to the athlete achieving a qualification standard. In addition, champions from the previous World Championships and the 2014 IAAF Diamond League receive an automatic bye. An automatic entry is also available to an Area Champion, the IAAF definition of an Area essentially being the specified continental areas of the world. The United States is part of the North American, Central American and Caribbean Athletic Association, which held its championship August 79, 2015 in San Jose, Costa Rica where 20 athletes qualified. The deadline for entries was August 10. The final team membership as submitted to the IAAF was announced on August 10, 2015.
Passage 3:Father Paolo Baldi (David Threlfall) is a priest torn between his interest in investigation and detective work, and the secluded life of a priest. On sabbatical from the Franciscan Order, he takes up amateur sleuthing and befriends DI Tina Mahon (Tina Kellegher for the first four series, then Tara Flynn), a member of the Gardai. Both her superior, DS Rynne (Owen Roe), and Baldi's spiritual director, Father Troy (T. P. McKenna), would prefer that he end his sabbatical and return to the Order. Father Baldi has an unfortunate knack of becoming involved in murder enquires, usually by his friendship with one of those involved. His gentle, reassuring behaviour and the Seal of the Confessional encourages participants to open up to him.
