QUES: In simple terms the structure of the Alps consists of layers of rock of European, African and oceanic (Tethyan) origin. The bottom nappe structure is of continental European origin, above which are stacked marine sediment nappes, topped off by nappes derived from the African plate. The Matterhorn is an example of the ongoing orogeny and shows evidence of great folding. The tip of the mountain consists of gneisses from the African plate; the base of the peak, below the glaciated area, consists of European basement rock. The sequence of Tethyan marine sediments and their oceanic basement is sandwiched between rock derived from the African and European plates.

What is an example of the ongoing orogeny?
What is the answer?
ANS: The Matterhorn
QUES: The Augustan settlement built upon a cultural shift in Roman society. In the middle Republican era, even Scipio's tentative hints that he might be Jupiter's special protege sat ill with his colleagues. Politicians of the later Republic were less equivocal; both Sulla and Pompey claimed special relationships with Venus. Julius Caesar went further, and claimed her as his ancestress. Such claims suggested personal character and policy as divinely inspired; an appointment to priesthood offered divine validation. In 63 BC, Julius Caesar's appointment as pontifex maximus "signaled his emergence as a major player in Roman politics". Likewise, political candidates could sponsor temples, priesthoods and the immensely popular, spectacular public ludi and munera whose provision became increasingly indispensable to the factional politics of the Late Republic. Under the principate, such opportunities were limited by law; priestly and political power were consolidated in the person of the princeps ("first citizen").

How were opportunities limited in the principate for the citizens of Rome?
What is the answer?
ANS: by law
QUES: Since annelids are soft-bodied, their fossils are rare mostly jaws and the mineralized tubes that some of the species secreted. Although some late Ediacaran fossils may represent annelids, the oldest known fossil that is identified with confidence comes from about 518 million years ago in the early Cambrian period. Fossils of most modern mobile polychaete groups appeared by the end of the Carboniferous, about 299 million years ago. Palaeontologists disagree about whether some body fossils from the mid Ordovician, about 472 to 461 million years ago, are the remains of oligochaetes, and the earliest indisputable fossils of the group appear in the Tertiary period, which began 65 million years ago.

What period started around 472 million years ago?
What is the answer?
ANS:
the mid Ordovician
