Question: What criteria is used to decide when Armenia was in its heyday?, Context: The first geographical entity that was called Armenia by neighboring peoples (such as by Hecataeus of Miletus and on the Achaemenid Behistun Inscription) was established in the late 6th century BC under the Orontid dynasty within the Achaemenid Persian Empire as part of the latters' territories, and which later became a kingdom. At its zenith (95–65 BC), the state extended from the Caucasus all the way to what is now central Turkey, Lebanon, and northern Iran. The imperial reign of Tigranes the Great is thus the span of time during which Armenia itself conquered areas populated by other peoples.

Answer: the span of time during which Armenia itself conquered areas populated by other peoples

Question: What did plant biologist consider stroma-containing tubules to be?, Context: The chloroplast membranes sometimes protrude out into the cytoplasm, forming a stromule, or stroma-containing tubule. Stromules are very rare in chloroplasts, and are much more common in other plastids like chromoplasts and amyloplasts in petals and roots, respectively. They may exist to increase the chloroplast's surface area for cross-membrane transport, because they are often branched and tangled with the endoplasmic reticulum. When they were first observed in 1962, some plant biologists dismissed the structures as artifactual, claiming that stromules were just oddly shaped chloroplasts with constricted regions or dividing chloroplasts. However, there is a growing body of evidence that stromules are functional, integral features of plant cell plastids, not merely artifacts.

Answer:
oddly shaped chloroplasts
