Problem: Animal:

The Platyzoa include the phylum Platyhelminthes, the flatworms. These were originally considered some of the most primitive Bilateria, but it now appears they developed from more complex ancestors. A number of parasites are included in this group, such as the flukes and tapeworms. Flatworms are acoelomates, lacking a body cavity, as are their closest relatives, the microscopic Gastrotricha. The other platyzoan phyla are mostly microscopic and pseudocoelomate. The most prominent are the Rotifera or rotifers, which are common in aqueous environments. They also include the Acanthocephala or spiny-headed worms, the Gnathostomulida, Micrognathozoa, and possibly the Cycliophora. These groups share the presence of complex jaws, from which they are called the Gnathifera.

What does acoelomates mean?

A: lacking a body cavity


Problem: Architectural classicism is heavily represented in all districts of the city, particularly in Downtown, the Fan, and the Museum District. Several notable classical architects have designed buildings in Richmond. The Virginia State Capitol was designed by Thomas Jefferson and Charles-Louis Clérisseau in 1785. It is the second-oldest US statehouse in continuous use (after Maryland's) and was the first US government building built in the neo-classical style of architecture, setting the trend for other state houses and the federal government buildings (including the White House and The Capitol) in Washington, D.C.
