Problem: About 80% of undergraduates and 20% of graduate students live on campus. The majority of the graduate students on campus live in one of four graduate housing complexes on campus, while all on-campus undergraduates live in one of the 29 residence halls. Because of the religious affiliation of the university, all residence halls are single-sex, with 15 male dorms and 14 female dorms. The university maintains a visiting policy (known as parietal hours) for those students who live in dormitories, specifying times when members of the opposite sex are allowed to visit other students' dorm rooms; however, all residence halls have 24-hour social spaces for students regardless of gender. Many residence halls have at least one nun and/or priest as a resident. There are no traditional social fraternities or sororities at the university, but a majority of students live in the same residence hall for all four years. Some intramural sports are based on residence hall teams, where the university offers the only non-military academy program of full-contact intramural American football. At the end of the intramural season, the championship game is played on the field in Notre Dame Stadium.
What amount of the graduate student body at Notre Dame live on the campus?
The answer is the following: 20%

Problem: The soft AC format may soon be facing the demographic pressures that the jazz and big band formats faced in the 1960s and 1970s and that the oldies format is starting to face today, with the result that one may hear soft AC less on over-the-air radio and more on satellite radio systems in coming years. Much of the music and artists that were traditionally played on soft AC stations have been relegated to the adult standards format, which is itself disappearing because of aging demographics. Some soft AC stations have found a niche by incorporating more oldies into their playlists and are more open to playing softer songs that fit the "traditional" definition of AC.
Certain soft AC stations have found a niche on the radio by doing what?
The answer is the following: incorporating more oldies

Problem: The ordinary half-wave dipole is probably the most widely used antenna design. This consists of two 1⁄4-wavelength elements arranged end-to-end, and lying along essentially the same axis (or collinear), each feeding one side of a two-conductor transmission wire. The physical arrangement of the two elements places them 180 degrees out of phase, which means that at any given instant one of the elements is driving current into the transmission line while the other is pulling it out. The monopole antenna is essentially one half of the half-wave dipole, a single 1⁄4-wavelength element with the other side connected to ground or an equivalent ground plane (or counterpoise). Monopoles, which are one-half the size of a dipole, are common for long-wavelength radio signals where a dipole would be impractically large. Another common design is the folded dipole, which is essentially two dipoles placed side-by-side and connected at their ends to make a single one-wavelength antenna.
What popular type combines more that one antenna?
The answer is the following: folded dipole

Problem: To the west, settlements in the Zagros basin experience lower temperatures, severe winters with below zero average daily temperatures and heavy snowfall. The eastern and central basins are arid, with less than 200 mm (7.9 in) of rain, and have occasional deserts. Average summer temperatures rarely exceed 38 °C (100.4 °F). The coastal plains of the Persian Gulf and Gulf of Oman in southern Iran have mild winters, and very humid and hot summers. The annual precipitation ranges from 135 to 355 mm (5.3 to 14.0 in).
The eastern and central basins of Iran experience how much annual precipitation?
The answer is the following:
less than 200 mm (7.9 in) of rain
