Kouros (male youth) is the modern term given to those representations of standing male youths which first appear in the archaic period in Greece. This type served certain religious needs and was first proposed for what was previously thought to be depictions of Apollo. The first statues are certainly still and formal. The formality of their stance seems to be related with the Egyptian precedent, but it was accepted for a good reason. The sculptors had a clear idea of what a young man is, and embodied the archaic smile of good manners, the firm and springy step, the balance of the body, dignity, and youthful happiness. When they tried to depict the most abiding qualities of men, it was because men had common roots with the unchanging gods. The adoption of a standard recognizable type for a long time, is probably because nature gives preference in survival of a type which has long be adopted by the climatic conditions, and also due to the general Greek belief that nature expresses itself in ideal forms that can be imagined and represented. These forms expressed immortality. Apollo was the immortal god of ideal balance and order. His shrine in Delphi, that he shared in winter with Dionysius had the inscriptions: γνῶθι σεαυτόν (gnōthi seautón="know thyself") and μηδὲν ἄγαν (mēdén ágan, "nothing in excess"), and ἐγγύα πάρα δ'ἄτη (eggýa pára d'atē, "make a pledge and mischief is nigh").

Starting in 2006, Apple's industrial design shifted to favor aluminum, which was used in the construction of the first MacBook Pro. Glass was added in 2008 with the introduction of the unibody MacBook Pro. These materials are billed as environmentally friendly. The iMac, MacBook Pro, MacBook Air, and Mac Mini lines currently all use aluminum enclosures, and are now made of a single unibody. Chief designer Jonathan Ive continues to guide products towards a minimalist and simple feel, including eliminating of replaceable batteries in notebooks. Multi-touch gestures from the iPhone's interface have been applied to the Mac line in the form of touch pads on notebooks and the Magic Mouse and Magic Trackpad for desktops.
Are aluminum and glass considered to be environmentally friendly or environmentally harmful?
****

The problem: Answer a question about this article:
Chinese troops suffered from deficient military equipment, serious logistical problems, overextended communication and supply lines, and the constant threat of UN bombers. All of these factors generally led to a rate of Chinese casualties that was far greater than the casualties suffered by UN troops. The situation became so serious that, on November 1951, Zhou Enlai called a conference in Shenyang to discuss the PVA's logistical problems. At the meeting it was decided to accelerate the construction of railways and airfields in the area, to increase the number of trucks available to the army, and to improve air defense by any means possible. These commitments did little to directly address the problems confronting PVA troops.
Did the UN troops or Chinese troops experience more war casualties?
****
The answer:
Chinese troops
