Problem: Please answer a question about the following article about Annelid:
However, leeches and their closest relatives have a body structure that is very uniform within the group but significantly different from that of other annelids, including other members of the Clitellata. In leeches there are no septa, the connective tissue layer of the body wall is so thick that it occupies much of the body, and the two coelomata are widely separated and run the length of the body. They function as the main blood vessels, although they are side-by-side rather than upper and lower. However, they are lined with mesothelium, like the coelomata and unlike the blood vessels of other annelids. Leeches generally use suckers at their front and rear ends to move like inchworms. The anus is on the upper surface of the pygidium.
What type of annelids are very different from others?
A: leeches and their closest relatives
Problem: Please answer a question about the following article about Professional wrestling:
An individual wrestler may sometimes use their real name, or a minor variation of it, for much of their career, such as Angelo Poffo, Ernie Ladd, Verne Gagne, Bret Hart, and Randy Orton. Others can keep one ring name for their entire career (cases in point include Chris Jericho, Shawn Michaels, CM Punk and Ricky Steamboat), or may change from time to time to better suit the demands of the audience or company. Sometimes a character is owned and trademarked by the company, forcing the wrestler to find a new one when they leave (although a simple typeset change, such as changing Rhyno to Rhino, can usually get around this), and sometimes a character is owned by the wrestler. Sometimes, a wrestler may change their legal name in order to obtain ownership of their ring name (examples include Andrew Martin and Warrior). Many wrestlers (such as The Rock and The Undertaker) are strongly identified with their character, even responding to the name in public or between friends. It's actually considered proper decorum for fellow wrestlers to refer to each other by their stage names/characters rather than their birth/legal names, unless otherwise introduced. A professional wrestling character's popularity can grow to the point that it makes appearances in other media (see Hulk Hogan and El Santo) or even give the performer enough visibility to enter politics (Antonio Inoki and Jesse Ventura, among others).
How can a wrestler get around changing their ring name entirely?
A: typeset change
Problem: Please answer a question about the following article about The Bronx:
The Bronx street grid is irregular. Like the northernmost part of upper Manhattan, the West Bronx's hilly terrain leaves a relatively free-style street grid. Much of the West Bronx's street numbering carries over from upper Manhattan, but does not match it exactly; East 132nd Street is the lowest numbered street in the Bronx. This dates from the mid-19th century when the southwestern area of Westchester County west of the Bronx River, was incorporated into New York City and known as the Northside.
What part of Manhattan are the West Bronx's streets similar to?
A: northernmost part of upper Manhattan
Problem: Please answer a question about the following article about Antenna (radio):
The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.
What is the reason for the receiver seeing both the ral antenna and image of the antenna?
A:
reflection
