Problem: Annelid:

The brain generally forms a ring round the pharynx (throat), consisting of a pair of ganglia (local control centers) above and in front of the pharynx, linked by nerve cords either side of the pharynx to another pair of ganglia just below and behind it. The brains of polychaetes are generally in the prostomium, while those of clitellates are in the peristomium or sometimes the first segment behind the peristomium. In some very mobile and active polychaetes the brain is enlarged and more complex, with visible hindbrain, midbrain and forebrain sections. The rest of the central nervous system is generally "ladder-like", consisting of a pair of nerve cords that run through the bottom part of the body and have in each segment paired ganglia linked by a transverse connection. From each segmental ganglion a branching system of local nerves runs into the body wall and then encircles the body. However, in most polychaetes the two main nerve cords are fused, and in the tube-dwelling genus Owenia the single nerve chord has no ganglia and is located in the epidermis.

Ultimately, Lee spent over two and a half years writing To Kill a Mockingbird. The book was published on July 11, 1960. After rejecting the "Watchman" title, it was initially re-titled Atticus, but Lee renamed it "To Kill a Mockingbird" to reflect that the story went beyond just a character portrait. The editorial team at Lippincott warned Lee that she would probably sell only several thousand copies. In 1964, Lee recalled her hopes for the book when she said, "I never expected any sort of success with 'Mockingbird.' ... I was hoping for a quick and merciful death at the hands of the reviewers but, at the same time, I sort of hoped someone would like it enough to give me encouragement. Public encouragement. I hoped for a little, as I said, but I got rather a whole lot, and in some ways this was just about as frightening as the quick, merciful death I'd expected." Instead of a "quick and merciful death", Reader's Digest Condensed Books chose the book for reprinting in part, which gave it a wide readership immediately. Since the original publication, the book has never been out of print.
How long did Lee spend writing the book?
A: over two and a half years

Question: Depending on a number of considerations, a company may apply for and be granted a patent for the drug, or the process of producing the drug, granting exclusivity rights typically for about 20 years. However, only after rigorous study and testing, which takes 10 to 15 years on average, will governmental authorities grant permission for the company to market and sell the drug. Patent protection enables the owner of the patent to recover the costs of research and development through high profit margins for the branded drug. When the patent protection for the drug expires, a generic drug is usually developed and sold by a competing company. The development and approval of generics is less expensive, allowing them to be sold at a lower price. Often the owner of the branded drug will introduce a generic version before the patent expires in order to get a head start in the generic market. Restructuring has therefore become routine, driven by the patent expiration of products launched during the industry's "golden era" in the 1990s and companies' failure to develop sufficient new blockbuster products to replace lost revenues.
Is there an answer to this question: Governments grant permission to market drugs after how many years?

Answer: 10 to 15 years on average
