Problem: Nearly all polychaetes have parapodia that function as limbs, while other major annelid groups lack them. Parapodia are unjointed paired extensions of the body wall, and their muscles are derived from the circular muscles of the body. They are often supported internally by one or more large, thick chetae. The parapodia of burrowing and tube-dwelling polychaetes are often just ridges whose tips bear hooked chetae. In active crawlers and swimmers the parapodia are often divided into large upper and lower paddles on a very short trunk, and the paddles are generally fringed with chetae and sometimes with cirri (fused bundles of cilia) and gills.
What kind of parapodia do burrowing annelids often have?

Answer: ridges whose tips bear hooked chetae

Problem: Early court cases focused on the liability of Internet service providers (ISPs) for hosting, transmitting or publishing user-supplied content that could be actioned under civil or criminal law, such as libel, defamation, or pornography. As different content was considered in different legal systems, and in the absence of common definitions for "ISPs," "bulletin boards" or "online publishers," early law on online intermediaries' liability varied widely from country to country. The first laws on online intermediaries' liability were passed from the mid-1990s onwards.[citation needed]
