Theatrical piracy took on new life with the 1856 amendments to the United States copyright laws. Before 1856, published playscripts were not protected from unauthorized performance, only from unauthorized physical duplication. Publication effectively allowed the public to use the play in any way not explicitly forbidden by statute; by contrast, plays that had been performed but not printed and sold were considered unpublished and so continued to be protected by the law. Consequently, most playwrights never printed their works, seeking to prevent potential pirates from duplicating the texts and staging the plays. By extending copyright protection to performances of published plays, the 1856 amendments sought to encourage publication of playscripts, but the physical texts also became available to those who chose to duplicate them illegally.

The primary purpose of the passage is to

Rationale

evaluate an account of the evolution of various types of arthropods.

The passage primarily assesses Sidnie Manton's views on the evolutionary relationships among arthropods, highlighting both convergent evolution and shared characteristics. It examines how these different groups, despite similarities, may have evolved independently from ancestral forms.

A (explain how insects and crustaceans differ from chelicerates) YOUR ANSWER

While the passage touches on the differences among insects, crustaceans, and chelicerates, it does not focus specifically on explaining those differences. Instead, it emphasizes the evolutionary context and shared characteristics rather than a detailed comparison of the groups.

B (evaluate an account of the evolution of various types of arthropods) CORRECT

This choice accurately reflects the passage's purpose, as it critically examines Manton's argument about the independent evolution of arthropods and the implications of their shared traits. The discussion centers on evaluating different evolutionary perspectives rather than merely describing the organisms.

C (illustrate a case of convergent evolution among different types of arthropods) YOUR ANSWER

Although the passage mentions convergent evolution, it does not solely aim to illustrate this concept. Instead, it uses convergent evolution as a part of a broader evaluation of evolutionary relationships, which is not the primary purpose.

D (discuss various physiological features of insects, crustaceans, and chelicerates) YOUR ANSWER

The passage does include some discussion of physiological traits, like jointed exoskeletons and compound eyes. However, it does not primarily focus on these features but rather on their evolutionary implications, which is not in line with this choice.

E (identify underlying similarities in two contrasting theories regarding the evolution of certain arthropods) YOUR ANSWER

While the passage discusses similarities and differences, it does not explicitly present or compare two contrasting theories. Instead, it evaluates Manton's theory without detailing another opposing viewpoint, making this choice less accurate.

Conclusion

The passage serves to evaluate Sidnie Manton's account of arthropod evolution, focusing on the independent evolution of various arthropod groups despite their shared characteristics. By analyzing both convergent evolution and the neurological differences in vision, it provides a nuanced view of evolutionary processes rather than simply describing the organisms or their features.
