Problem: Czech language:

While Old Czech had a basic alphabet from which a general set of orthographical correspondences was drawn, it did not have a standard orthography. It also contained a number of sound clusters which no longer exist; allowing e (/j/) after soft consonants, which has since shifted to e (//), and allowing complex consonant clusters to be pronounced all at once rather than syllabically. A phonological phenomenon, Havlik's law (which began in Proto-Slavic and took various forms in other Slavic languages), appeared in Old Czech; counting backwards from the end of a clause, every odd-numbered yer was vocalized as a vowel, while the other yers disappeared.

How did Proto-Slavic let complex consonant clusters to be pronounced?

A: unanswerable

Problem: Race and ethnicity in the United States Census:

Race was asked differently in the Census 2000 in several other ways than previously. Most significantly, respondents were given the option of selecting one or more race categories to indicate racial identities. Data show that nearly seven million Americans identified as members of two or more races. Because of these changes, the Census 2000 data on race are not directly comparable with data from the 1990 census or earlier censuses. Use of caution is therefore recommended when interpreting changes in the racial composition of the US population over time.

What year was the last census before the Census 2000?
---
A: 1990

Problem: Insect:

Scarab beetles held religious and cultural symbolism in Old Egypt, Greece and some shamanistic Old World cultures. The ancient Chinese regarded cicadas as symbols of rebirth or immortality. In Mesopotamian literature, the epic poem of Gilgamesh has allusions to Odonata which signify the impossibility of immortality. Amongst the Aborigines of Australia of the Arrernte language groups, honey ants and witchety grubs served as personal clan totems. In the case of the 'San' bush-men of the Kalahari, it is the praying mantis which holds much cultural significance including creation and zen-like patience in waiting.:9

The praying mantis symbolizes patience and what else?
---
A: creation

Problem: University of Notre Dame:

The university first offered graduate degrees, in the form of a Master of Arts (MA), in the 18541855 academic year. The program expanded to include Master of Laws (LL.M.) and Master of Civil Engineering in its early stages of growth, before a formal graduate school education was developed with a thesis not required to receive the degrees. This changed in 1924 with formal requirements developed for graduate degrees, including offering Doctorate (PhD) degrees. Today each of the five colleges offer graduate education. Most of the departments from the College of Arts and Letters offer PhD programs, while a professional Master of Divinity (M.Div.) program also exists. All of the departments in the College of Science offer PhD programs, except for the Department of Pre-Professional Studies. The School of Architecture offers a Master of Architecture, while each of the departments of the College of Engineering offer PhD programs. The College of Business offers multiple professional programs including MBA and Master of Science in Accountancy programs. It also operates facilities in Chicago and Cincinnati for its executive MBA program. Additionally, the Alliance for Catholic Education program offers a Master of Education program where students study at the university during the summer and teach in Catholic elementary schools, middle schools, and high schools across the Southern United States for two school years.

In what year was a Master of Arts course first offered at Notre Dame?

A:
1854
