Problem: Antenna (radio):

High-gain antennas have the advantage of longer range and better signal quality, but must be aimed carefully at the other antenna. An example of a high-gain antenna is a parabolic dish such as a satellite television antenna. Low-gain antennas have shorter range, but the orientation of the antenna is relatively unimportant. An example of a low-gain antenna is the whip antenna found on portable radios and cordless phones. Antenna gain should not be confused with amplifier gain, a separate parameter measuring the increase in signal power due to an amplifying device.

Antennas with higher gain have what positive feature?
---
A: longer range


Problem: Einstein partially advocates Mach's principle in that distant stars explain inertia because they provide the gravitational field against which acceleration and inertia occur. But contrary to Leibniz's account, this warped space-time is as integral a part of an object as are its other defining characteristics, such as volume and mass. If one holds, contrary to idealist beliefs, that objects exist independently of the mind, it seems that relativistics commits them to also hold that space and temporality have exactly the same type of independent existence.
How does Einstein advocate Mach's principle?

Answer: partially


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although many species can reproduce asexually and use similar mechanisms to regenerate after severe injuries, sexual reproduction is the normal method in species whose reproduction has been studied. The minority of living polychaetes whose reproduction and lifecycles are known produce trochophore larvae, that live as plankton and then sink and metamorphose into miniature adults. Oligochaetes are full hermaphrodites and produce a ring-like cocoon around their bodies, in which the eggs and hatchlings are nourished until they are ready to emerge.
What annelids dislike hermaphrodites?
A: unanswerable


Context and question: State law codifies Oklahoma's state emblems and honorary positions; the Oklahoma Senate or House of Representatives may adopt resolutions designating others for special events and to benefit organizations. Currently the State Senate is waiting to vote on a change to the state's motto. The House passed HCR 1024, which will change the state motto from "Labor Omnia Vincit" to "Oklahoma-In God We Trust!" The author of the resolution stated that a constituent researched the Oklahoma Constitution and found no "official" vote regarding "Labor Omnia Vincit", therefore opening the door for an entirely new motto.
What was Oklahoma's state motto, before the state House bill might change it?
Answer: Labor Omnia Vincit


Question: Additionally, cable-ready TV sets can display HD content without using an external box. They have a QAM tuner built-in and/or a card slot for inserting a CableCARD.
Is there an answer to this question: What kind of built-in tuner will allow a cable-ready TV to display HD content without an external box?

Answer: QAM

The German Empire conquered Ukraine during World War I and was planning on either annexing it or installing a puppet king, but was defeated by the Entente, with major involvement by the Ukrainian Bolsheviks. After conquering the rest of Ukraine from the Whites, Ukraine joined the USSR and was enlarged (gaining Crimea and then Eastern Galicia), whence a process of Ukrainization was begun, with encouragement from Moscow.
What nation conquered Ukraine during the First World War?
A:
The German Empire
