Problem: Czech language:

Czech syntax has a subject–verb–object sentence structure. In practice, however, word order is flexible and used for topicalization and focus. Although Czech has a periphrastic passive construction (like English), colloquial word-order changes frequently produce the passive voice. For example, to change "Peter killed Paul" to "Paul was killed by Peter" the order of subject and object is inverted: Petr zabil Pavla ("Peter killed Paul") becomes "Paul, Peter killed" (Pavla zabil Petr). Pavla is in the accusative case, the grammatical object (in this case, the victim) of the verb.

What kind of passive construction does Czech have?
---
A: periphrastic


Problem: Tajikistan:

Sunni Islam of the Hanafi school has been officially recognized by the government since 2009. Tajikistan considers itself a secular state with a Constitution providing for freedom of religion. The Government has declared two Islamic holidays, Id Al-Fitr and Idi Qurbon, as state holidays. According to a U.S. State Department release and Pew research group, the population of Tajikistan is 98% Muslim. Approximately 87%–95% of them are Sunni and roughly 3% are Shia and roughly 7% are non-denominational Muslims. The remaining 2% of the population are followers of Russian Orthodoxy, Protestantism, Zoroastrianism and Buddhism. A great majority of Muslims fast during Ramadan, although only about one third in the countryside and 10% in the cities observe daily prayer and dietary restrictions.

Problem: Sahara:

People lived on the edge of the desert thousands of years ago since the last ice age. The Sahara was then a much wetter place than it is today. Over 30,000 petroglyphs of river animals such as crocodiles survive, with half found in the Tassili n'Ajjer in southeast Algeria. Fossils of dinosaurs, including Afrovenator, Jobaria and Ouranosaurus, have also been found here. The modern Sahara, though, is not lush in vegetation, except in the Nile Valley, at a few oases, and in the northern highlands, where Mediterranean plants such as the olive tree are found to grow. It was long believed that the region had been this way since about 1600 BCE, after shifts in the Earth's axis increased temperatures and decreased precipitation. However, this theory has recently been called into dispute, when samples taken from several 7 million year old sand deposits led scientists to reconsider the timeline for desertification.

What type of petroglyhps have been found in the Nile Valley?
