Article: Both the vertical and dipole antennas are simple in construction and relatively inexpensive. The dipole antenna, which is the basis for most antenna designs, is a balanced component, with equal but opposite voltages and currents applied at its two terminals through a balanced transmission line (or to a coaxial transmission line through a so-called balun). The vertical antenna, on the other hand, is a monopole antenna. It is typically connected to the inner conductor of a coaxial transmission line (or a matching network); the shield of the transmission line is connected to ground. In this way, the ground (or any large conductive surface) plays the role of the second conductor of a dipole, thereby forming a complete circuit. Since monopole antennas rely on a conductive ground, a so-called grounding structure may be employed to provide a better ground contact to the earth or which itself acts as a ground plane to perform that function regardless of (or in absence of) an actual contact with the earth.

Question: What is the foundation most often used when creating new antenna models?
Ans: dipole antenna

Article: Many ancient works, such as the Bible and the Greek tragedies,[citation needed] survive in hundreds of copies, and the relationship of each copy to the original may be unclear. Textual scholars have debated for centuries which sources are most closely derived from the original, hence which readings in those sources are correct.[citation needed] Although biblical books that are letters, like Greek plays, presumably had one original, the question of whether some biblical books, like the Gospels, ever had just one original has been discussed. Interest in applying textual criticism to the Qur'an has also developed after the discovery of the Sana'a manuscripts in 1972, which possibly date back to the 78th centuries.

Question: Why are scholars concerned with analysis of the Gospels over the letters?
Ans: biblical books that are letters, like Greek plays, presumably had one original

Article: New Delhi has one of India's largest bus transport systems. Buses are operated by the state-owned Delhi Transport Corporation (DTC), which owns largest fleet of compressed natural gas (CNG)-fueled buses in the world. Personal vehicles especially cars also form a major chunk of vehicles plying on New Delhi roads. New Delhi has the highest number of registered cars compared to any other metropolitan city in India. Taxis and Auto Rickshaws also ply on New Delhi roads in large numbers. New Delhi has one of the highest road density in India.

Question: What large metropolis has some of the highest road density in India?
Ans: New Delhi

Article: In the final decades of this era many plebeians grew poorer. The long military campaigns had forced citizens to leave their farms to fight, while their farms fell into disrepair. The landed aristocracy began buying bankrupted farms at discounted prices. As commodity prices fell, many farmers could no longer operate their farms at a profit. The result was the ultimate bankruptcy of countless farmers. Masses of unemployed plebeians soon began to flood into Rome, and thus into the ranks of the legislative assemblies. Their poverty usually led them to vote for the candidate who offered them the most. A new culture of dependency was emerging, in which citizens would look to any populist leader for relief.

Question: What caused the bankruptcy of many farmers during this era?
Ans:
commodity prices fell
