Problem: Symbiosis:

Another non-obligate symbiosis is known from encrusting bryozoans and hermit crabs that live in a close relationship. The bryozoan colony (Acanthodesia commensale) develops a cirumrotatory growth and offers the crab (Pseudopagurus granulimanus) a helicospiral-tubular extension of its living chamber that initially was situated within a gastropod shell.

What relationship is it considered when the bryozoans and hermit crabs do not live in a close relationship?

A: unanswerable


Problem: In the next centuries, Armenia was in the Persian Empire's sphere of influence during the reign of Tiridates I, the founder of the Arsacid dynasty of Armenia, which itself was a branch of the eponymous Arsacid dynasty of Parthia. Throughout its history, the kingdom of Armenia enjoyed both periods of independence and periods of autonomy subject to contemporary empires. Its strategic location between two continents has subjected it to invasions by many peoples, including the Assyrians (under Ashurbanipal, at around 669–627 BC, the boundaries of the Assyrian Empire reached as far as Armenia & the Caucasus Mountains), Medes, Achaemenid Persians, Greeks, Parthians, Romans, Sassanid Persians, Byzantines, Arabs, Seljuks, Mongols, Ottomans, successive Iranian Safavids, Afsharids, and Qajars, and the Russians.
What made Armenia so easily invadable?
---
Answer: strategic location between two continents


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Most electrification systems use overhead wires, but third rail is an option up to about 1,200 V. Third rail systems exclusively use DC distribution. The use of AC is not feasible because the dimensions of a third rail are physically very large compared with the skin depth that the alternating current penetrates to (0.3 millimetres or 0.012 inches) in a steel rail). This effect makes the resistance per unit length unacceptably high compared with the use of DC. Third rail is more compact than overhead wires and can be used in smaller-diameter tunnels, an important factor for subway systems.
What is physically more compact tird rail or overhead wires?
A: Third rail

QUES: Peaks in France, Italy and Switzerland lie in the "Houillière zone", which consists of basement with sediments from the Mesozoic Era. High "massifs" with external sedimentary cover are more common in the Western Alps and were affected by Neogene Period thin-skinned thrusting whereas the Eastern Alps have comparatively few high peaked massifs. Similarly the peaks in Switzerland extending to western Austria (Helvetic nappes) consist of thin-skinned sedimentary folding that detached from former basement rock.

When compared to the Western Alps, what area has few high peaked massifs?
What is the answer?
ANS:
Eastern Alps
