The ISS has been described as the most expensive single item ever constructed. In 2010 the cost was expected to be $150 billion. This includes NASAs budget of $58.7 billion (inflation-unadjusted) for the station from 1985 to 2015 ($72.4 billion in 2010 dollars), Russias $12 billion, Europes $5 billion, Japans $5 billion, Canadas $2 billion, and the cost of 36 shuttle flights to build the station; estimated at $1.4 billion each, or $50.4 billion in total. Assuming 20,000 person-days of use from 2000 to 2015 by two- to six-person crews, each person-day would cost $7.5 million, less than half the inflation-adjusted $19.6 million ($5.5 million before inflation) per person-day of Skylab.

How many more billions of dollars did Europe contribute to the cost of the ISS compared to Canada?
A: 3

In the mid-17th century, nuns from other monasteries in the Ukrainian and Belarusian lands were transferred to Novodevichy Convent, the first of whom was named Yelena Dyevochkina. In 1721, some of the aged nuns, who renounced the Old Believers movement, were given shelter. In 1724, the convent also housed a military hospital for the soldiers and officers of the Imperial Russian Army and an orphanage for female foundlings. By 1763, the convent housed 84 nuns, 35 lay sisters, and 78 sick patients and servants. Each year, the state provided the Novodevichy Convent with 1,500 rubles, 1,300 quarters of bread, and 680 rubles and 480 quarters of bread for more than 250 abandoned children. In 1812, Napoleon's army made an attempt to blow up the convent, but the nuns managed to save the cloister from destruction. In Tolstoy's War and Peace, Pierre was to be executed under the convent walls. In another novel of his, Anna Karenina, Konstantin Lyovin  meets his future wife Kitty ice-skating near the monastery walls. Indeed, the Maiden's Field  was the most popular skating-rink in 19th-century Moscow. Tolstoy himself enjoyed skating here when he lived nearby, in the district of Khamovniki. In 1871, the Filatyev brothers donated money for a shelter-school for the orphans of "ignoble origins". Also, the convent housed two almshouses for nuns and lay sisters. In early 1900s, the Cathedral was surveyed and restored by architect and preservationist Ivan Mashkov. By 1917, there were 51 nuns and 53 lay sisters residing in the Novodevichy Convent.

How many total nuns and lay sisters resided in Novodevichy Convent in 1917?
A: 104
