The desert zone also accounts for about a third of the state's surface area. The Chihuahuan Desert is an international biome that also extends into the neighboring Mexican state of Coahuila and into the U.S. states of Texas and New Mexico. The desert zone is mainly of flat topography with some small mountain ranges that run north to south. The desert in the state varies slightly with a small variant in climate. The lower elevations of the desert zone are found in the north along the Rio Grande which experience hotter temperatures in the summer and winter while the southern portion of the desert zone experiences cooler temperatures due to its higher elevation. The Samalayuca dunes cover an area of about 150 km2; it is an impressive site of the Chihuahuan Desert and is a protected area by the state due to unique species of plants and animals.
The Chihuahuan Desert also extends into which neighboring Mexican state?
****
The answer: Coahuila

Maintaining continuity with his predecessors, John XXIII continued the gradual reform of the Roman liturgy, and published changes that resulted in the 1962 Roman Missal, the last typical edition containing the Tridentine Mass established in 1570 by Pope Pius V at the request of the Council of Trent and whose continued use Pope Benedict XVI authorized in 2007, under the conditions indicated in his motu proprio Summorum Pontificum. In response to the directives of the Second Vatican Council, later editions of the Roman Missal present the 1970 form of the Roman Rite.

The problem: Answer a question about this article:
Scholar Patrick Chura, who suggests Emmett Till was a model for Tom Robinson, enumerates the injustices endured by the fictional Tom that Till also faced. Chura notes the icon of the black rapist causing harm to the representation of the "mythologized vulnerable and sacred Southern womanhood". Any transgressions by black males that merely hinted at sexual contact with white females during the time the novel was set often resulted in a punishment of death for the accused. Tom Robinson's trial was juried by poor white farmers who convicted him despite overwhelming evidence of his innocence, as more educated and moderate white townspeople supported the jury's decision. Furthermore, the victim of racial injustice in To Kill a Mockingbird was physically impaired, which made him unable to commit the act he was accused of, but also crippled him in other ways. Roslyn Siegel includes Tom Robinson as an example of the recurring motif among white Southern writers of the black man as "stupid, pathetic, defenseless, and dependent upon the fair dealing of the whites, rather than his own intelligence to save him". Although Tom is spared from being lynched, he is killed with excessive violence during an attempted escape from prison, shot seventeen times.
How did Tom Robinson die in the novel?
****
The answer: shot seventeen times

The problem: Answer a question about this article:
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?
****
The answer:
ridges whose tips bear hooked chetae
