Question: The distances passengers need to move within a large airport can be substantial. It is common for airports to provide moving walkways and buses. The Hartsfield–Jackson Atlanta International Airport has a tram that takes people through the concourses and baggage claim. Major airports with more than one terminal offer inter-terminal transportation, such as Mexico City International Airport, where the domestic building of Terminal 1 is connected by Aerotrén to Terminal 2, on the other side of the airport.
Is there an answer to this question: Name one airport that offers inter-terminal transportation.

Answer: Mexico City International Airport


Question: While most Hokkien morphemes have standard designated characters, they are not always etymological or phono-semantic. Similar-sounding, similar-meaning or rare characters are commonly borrowed or substituted to represent a particular morpheme. Examples include "beautiful" (美 bí is the literary form), whose vernacular morpheme suí is represented by characters like 媠 (an obsolete character), 婎 (a vernacular reading of this character) and even 水 (transliteration of the sound suí), or "tall" (高 ko is the literary form), whose morpheme kôan is 懸. Common grammatical particles are not exempt; the negation particle m̄ (not) is variously represented by 毋, 呣 or 唔, among others. In other cases, characters are invented to represent a particular morpheme (a common example is the character 𪜶 in, which represents the personal pronoun "they"). In addition, some characters have multiple and unrelated pronunciations, adapted to represent Hokkien words. For example, the Hokkien word bah ("meat") has been reduced to the character 肉, which has etymologically unrelated colloquial and literary readings (he̍k and jio̍k, respectively). Another case is the word 'to eat,' chia̍h, which is often transcribed in Taiwanese newspapers and media as 呷 (a Mandarin transliteration, xiā, to approximate the Hokkien term), even though its recommended character in dictionaries is 食.

Answer: Similar-sounding, similar-meaning or rare characters


Question: The similarities between Czech and Slovak led to the languages being considered a single language by a group of 19th-century scholars who called themselves "Czechoslavs" (Čechoslováci), believing that the peoples were connected in a way which excluded German Bohemians and (to a lesser extent) Hungarians and other Slavs. During the First Czechoslovak Republic (1918–1938), although "Czechoslovak" was designated as the republic's official language both Czech and Slovak written standards were used. Standard written Slovak was partially modeled on literary Czech, and Czech was preferred for some official functions in the Slovak half of the republic. Czech influence on Slovak was protested by Slovak scholars, and when Slovakia broke off from Czechoslovakia in 1938 as the Slovak State (which then aligned with Nazi Germany in World War II) literary Slovak was deliberately distanced from Czech. When the Axis powers lost the war and Czechoslovakia reformed, Slovak developed somewhat on its own (with Czech influence); during the Prague Spring of 1968, Slovak gained independence from (and equality with) Czech. Since then, "Czechoslovak" refers to improvised pidgins of the languages which have arisen from the decrease in mutual intelligibility.

Answer: unanswerable


Question: The light from LEDs can be modulated very quickly so they are used extensively in optical fiber and free space optics communications. This includes remote controls, such as for TVs, VCRs, and LED Computers, where infrared LEDs are often used. Opto-isolators use an LED combined with a photodiode or phototransistor to provide a signal path with electrical isolation between two circuits. This is especially useful in medical equipment where the signals from a low-voltage sensor circuit (usually battery-powered) in contact with a living organism must be electrically isolated from any possible electrical failure in a recording or monitoring device operating at potentially dangerous voltages. An optoisolator also allows information to be transferred between circuits not sharing a common ground potential.
Is there an answer to this question: What is an example of a device that uses free space optic communications?

Answer:
remote controls
