Problem: Text: Identical twins Susan Evers and Sharon McKendrick (Hayley Mills) meet at Miss Inch's Summer Camp for Girls, unaware that they are sisters. Their identical appearance initially creates rivalry, and they pull pranks on each other, culminating in the camp dance being ruined. As punishment, Miss Inch decides that they must live together in the isolated ''Serendipity'' cabin (and eat together at an ''Isolation Table'') for the remainder of the camp season. After discovering that they both come from single-parent homes, they soon realize they are twin sisters and that their parents, Mitchell ''Mitch'' Evers (Brian Keith) and Margaret ''Maggie'' McKendrick (Maureen O'Hara), divorced shortly after their birth, with each parent having custody of one of them. The twins, each eager to meet the parent she never knew, decide to switch places. Susan gives Sharon a matching haircut and has her bite her nails. They also take a crash-course getting to know each other while learning about each other's personalities and ways of life.

Question: are the twins in the parent trap the same person?

OPTIONS:
- no
- yes
A: yes

Problem: Text: Irish-American Catholics served on both sides of the American Civil War (1861--1865) as officers, volunteers and draftees. Immigration due to the Irish Great Famine (1845--1852) had provided many thousands of men as potential recruits although issues of race, religion, pacifism and personal allegiance created some resistance to service. A significant body of these Irishmen later used the military experience gained in the American Civil War to fight against the British Empire with the goal of establishing an Irish Republic as members of the Irish Republican Brotherhood, the Fenian Brotherhood and Clan na Gael. In addition very large numbers of Scots-Irish Protestants were involved in the American Civil War, especially the Confederacy.
