Problem: Antenna (radio):

Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength.

What will you be matching with the receiving antenna's polarization?

A: transmitter

Problem: In 179 BC Philip died. His talented and ambitious son, Perseus, took the throne and showed a renewed interest in conquering Greece. With her Greek allies facing a major new threat, Rome declared war on Macedonia again, starting the Third Macedonian War. Perseus initially had some success against the Romans. However, Rome responded by sending a stronger army. This second consular army decisively defeated the Macedonians at the Battle of Pydna in 168 BC and the Macedonians duly capitulated, ending the war.
Who was next in line to the throne at the time of Philip's death?

Answer: Perseus

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Primary (or elementary) education consists of the first five to seven years of formal, structured education. In general, primary education consists of six to eight years of schooling starting at the age of five or six, although this varies between, and sometimes within, countries. Globally, around 89% of children aged six to twelve are enrolled in primary education, and this proportion is rising. Under the Education For All programs driven by UNESCO, most countries have committed to achieving universal enrollment in primary education by 2015, and in many countries, it is compulsory. The division between primary and secondary education is somewhat arbitrary, but it generally occurs at about eleven or twelve years of age. Some education systems have separate middle schools, with the transition to the final stage of secondary education taking place at around the age of fourteen. Schools that provide primary education, are mostly referred to as primary schools or elementary schools. Primary schools are often subdivided into infant schools and junior school.
What is not another term used for Primary education?
A: unanswerable

Context and question: For much of the eighteenth century, France approached its wars in the same way. It would let colonies defend themselves or would offer only minimal help (sending them limited numbers of troops or inexperienced soldiers), anticipating that fights for the colonies would most likely be lost anyway. This strategy was to a degree forced upon France: geography, coupled with the superiority of the British navy, made it difficult for the French navy to provide significant supplies and support to French colonies. Similarly, several long land borders made an effective domestic army imperative for any French ruler. Given these military necessities, the French government, unsurprisingly, based its strategy overwhelmingly on the army in Europe: it would keep most of its army on the continent, hoping for victories closer to home. The plan was to fight to the end of hostilities and then, in treaty negotiations, to trade territorial acquisitions in Europe to regain lost overseas possessions. This approach did not serve France well in the war, as the colonies were indeed lost, but although much of the European war went well, by its end France had few counterbalancing European successes.
How much effort did France put into wars to defend its colonies?
Answer: It would let colonies defend themselves or would offer only minimal help

Question: Mutualism or interspecies reciprocal altruism is a relationship between individuals of different species where both individuals benefit. In general, only lifelong interactions involving close physical and biochemical contact can properly be considered symbiotic. Mutualistic relationships may be either obligate for both species, obligate for one but facultative for the other, or facultative for both. Many biologists restrict the definition of symbiosis to close mutualist relationships.
Is there an answer to this question: What mutualistic relationships fit the the definition of symbiosis?

Answer: unanswerable

QUES: Classified as a Subtropical Mediterranean climate (Koppen Csb), Santa Monica enjoys an average of 310 days of sunshine a year. It is located in USDA plant hardiness zone 11a. Because of its location, nestled on the vast and open Santa Monica Bay, morning fog is a common phenomenon in May, June and early July (caused by ocean temperature variations and currents). Like other inhabitants of the greater Los Angeles area, residents have a particular terminology for this phenomenon: the "May Gray" and the "June Gloom". Overcast skies are common during June mornings, but usually the strong sun burns the fog off by noon. In the late winter/early summer, daily fog is a phenomenon too. It happens suddenly and it may last some hours or past sunset time. Nonetheless, it will sometimes stay cloudy and cool all day during June, even as other parts of the Los Angeles area enjoy sunny skies and warmer temperatures. At times, the sun can be shining east of 20th Street, while the beach area is overcast. As a general rule, the beach temperature is from 5 to 10 degrees Fahrenheit (3 to 6 degrees Celsius) cooler than it is inland during summer days, and 510 degrees warmer during winter nights.
