[EX Q]: Boston has been a noted religious center from its earliest days. The Roman Catholic Archdiocese of Boston serves nearly 300 parishes and is based in the Cathedral of the Holy Cross (1875) in the South End, while the Episcopal Diocese of Massachusetts, with the Cathedral Church of St. Paul (1819) as its episcopal seat, serves just under 200 congregations. Unitarian Universalism has its headquarters on Beacon Hill. The Christian Scientists are headquartered in Back Bay at the Mother Church (1894). The oldest church in Boston is First Church in Boston, founded in 1630. King's Chapel, the city's first Anglican church, was founded in 1686 and converted to Unitarianism in 1785. Other churches include Christ Church (better known as Old North Church, 1723), the oldest church building in the city, Trinity Church (1733), Park Street Church (1809), Old South Church (1874), Jubilee Christian Church and Basilica and Shrine of Our Lady of Perpetual Help on Mission Hill (1878).

[EX Q]: Copper is an essential trace element in plants and animals, but not some microorganisms. The human body contains copper at a level of about 1.4 to 2.1 mg per kg of body mass. Stated differently, the RDA for copper in normal healthy adults is quoted as 0.97 mg/day and as 3.0 mg/day. Copper is absorbed in the gut, then transported to the liver bound to albumin. After processing in the liver, copper is distributed to other tissues in a second phase. Copper transport here involves the protein ceruloplasmin, which carries the majority of copper in blood. Ceruloplasmin also carries copper that is excreted in milk, and is particularly well-absorbed as a copper source. Copper in the body normally undergoes enterohepatic circulation (about 5 mg a day, vs. about 1 mg per day absorbed in the diet and excreted from the body), and the body is able to excrete some excess copper, if needed, via bile, which carries some copper out of the liver that is not then reabsorbed by the intestine.
[EX A]: What is the level of copper in the human body?

[EX Q]: The country's literacy level stands at 85% of the whole population. Preschool, which targets children from age three to five, is an integral component of the education system and is a key requirement for admission to Standard One (First Grade). At the end of primary education, pupils sit the Kenya Certificate of Primary Education (KCPE), which determines those who proceed to secondary school or vocational training. The result of this examination is needed for placement at secondary school. Primary school age is 6/7-13/14 years. For those who proceed to secondary level, there is a national examination at the end of Form Four – the Kenya Certificate of Secondary Education (KCSE), which determines those proceeding to the universities, other professional training or employment. Students sit examinations in eight subjects of their choosing. However, English, Kiswahili (languages) and mathematics are compulsory subjects.
