How common are carbonates and deposits in North America?, Context: To the north of Africa the Tethys Sea continued to narrow. Broad shallow seas advanced across central North America (the Western Interior Seaway) and Europe, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic. Mid-ocean ridge activity—or rather, the circulation of seawater through the enlarged ridges—enriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur in Europe and China. In the area that is now India, massive lava beds called the Deccan Traps were laid down in the very late Cretaceous and early Paleocene.

Which of the following people was highest in status: Princess Marcelina, Thomas Albrecht, or Solange?, Context: Some of his friends provided music at his request; among them, Potocka sang and Franchomme played the cello. Chopin requested that his body be opened after death (for fear of being buried alive) and his heart returned to Warsaw where it rests at the Church of the Holy Cross. He also bequeathed his unfinished notes on a piano tuition method, Projet de méthode, to Alkan for completion. On 17 October, after midnight, the physician leaned over him and asked whether he was suffering greatly. "No longer", he replied. He died a few minutes before two o'clock in the morning. Those present at the deathbed appear to have included his sister Ludwika, Princess Marcelina Czartoryska, Sand's daughter Solange, and his close friend Thomas Albrecht. Later that morning, Solange's husband Clésinger made Chopin's death mask and a cast of his left hand.
