Changes in secondary sex characteristics include every change that is not directly related to sexual reproduction. In males, these changes involve appearance of pubic, facial, and body hair, deepening of the voice, roughening of the skin around the upper arms and thighs, and increased development of the sweat glands. In females, secondary sex changes involve elevation of the breasts, widening of the hips, development of pubic and underarm hair, widening of the areolae, and elevation of the nipples. The changes in secondary sex characteristics that take place during puberty are often referred to in terms of five Tanner stages, named after the British pediatrician who devised the categorization system.
Is deepening of the voice in males a primary or secondary sex characteristic?
****
The answer: secondary

The team's commitment to contend was complete when Green made a midseason deal on June 15 to shore up the starting rotation due to injuries to Rick Reuschel (5–5) and Sanderson. The deal brought 1979 NL Rookie of the Year pitcher Rick Sutcliffe from the Cleveland Indians. Joe Carter (who was with the Triple-A Iowa Cubs at the time) and center fielder Mel Hall were sent to Cleveland for Sutcliffe and back-up catcher Ron Hassey (.333 with Cubs in 1984). Sutcliffe (5–5 with the Indians) immediately joined Sanderson (8–5 3.14), Eckersley (10–8 3.03), Steve Trout (13–7 3.41) and Dick Ruthven (6–10 5.04) in the starting rotation. Sutcliffe proceeded to go 16–1 for Cubs and capture the Cy Young Award.
Why did Green make a deal to shore up the starting rotation?
****
The answer: due to injuries to Rick Reuschel (5–5) and Sanderson

Bonaparte began with an army of 13,000 men; 1,500 were reported missing, 1,200 died in combat, and thousands perished from disease—mostly bubonic plague. He failed to reduce the fortress of Acre, so he marched his army back to Egypt in May. To speed up the retreat, Bonaparte ordered plague-stricken men to be poisoned with opium; the number who died remains disputed, ranging from a low of 30 to a high of 580. He also brought out 1,000 wounded men. Back in Egypt on 25 July, Bonaparte defeated an Ottoman amphibious invasion at Abukir.
To speed his retreat to Egypt, Napoleon ordered the poisoning of sick men with what substance?
****
The answer: opium


The problem: Answer a question about this article:
The term "bacteria" was traditionally applied to all microscopic, single-cell prokaryotes. However, molecular systematics showed prokaryotic life to consist of two separate domains, originally called Eubacteria and Archaebacteria, but now called Bacteria and Archaea that evolved independently from an ancient common ancestor. The archaea and eukaryotes are more closely related to each other than either is to the bacteria. These two domains, along with Eukarya, are the basis of the three-domain system, which is currently the most widely used classification system in microbiolology. However, due to the relatively recent introduction of molecular systematics and a rapid increase in the number of genome sequences that are available, bacterial classification remains a changing and expanding field. For example, a few biologists argue that the Archaea and Eukaryotes evolved from Gram-positive bacteria.
What are two main groups of prokaryotic organisms are divided into?
****
The answer:
Eubacteria and Archaebacteria
