Here is a question about this article: Internal courtyards became more rare, except beside the stables, and the functional parts of the building were placed at the sides, or in separate buildings nearby hidden by trees. The views to and from the front and rear of the main block were concentrated on, with the side approaches usually much less important. The roof was typically invisible from the ground, though domes were sometimes visible in grander buildings. The roofline was generally clear of ornament except for a balustrade or the top of a pediment. Columns or pilasters, often topped by a pediment, were popular for ornament inside and out, and other ornament was generally geometrical or plant-based, rather than using the human figure.
What is the answer to this question: What designs did ornament use to avoid using the human figure?
****
So... geometrical or plant-based


Here is a question about this article: 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 is the answer to this question: What mostly affects polarization?

So... Reflections


Here is a question about this article: Some forms of Greek before the Koine Greek period are reconstructed as having aspirated stops. The Classical Attic dialect of Ancient Greek had a three-way distinction in stops like Eastern Armenian: /t tʰ d/. These stops were called ψιλά, δασέα, μέσα "thin, thick, middle" by Koine Greek grammarians.
What is the answer to this question: Early Greek (before Koine) have been redone with what?
****
So...
aspirated stops.
