In the Graeco-Roman world, practitioners of magic were known as magi (singular magus), a "foreign" title of Persian priests. Apuleius, defending himself against accusations of casting magic spells, defined the magician as "in popular tradition (more vulgari)... someone who, because of his community of speech with the immortal gods, has an incredible power of spells (vi cantaminum) for everything he wishes to." Pliny the Elder offers a thoroughly skeptical "History of magical arts" from their supposed Persian origins to Nero's vast and futile expenditure on research into magical practices in an attempt to control the gods. Philostratus takes pains to point out that the celebrated Apollonius of Tyana was definitely not a magus, "despite his special knowledge of the future, his miraculous cures, and his ability to vanish into thin air".
What word was used by the Romans for practitioners of magic?
A: magi

The Eritrean highway system is named according to the road classification. The three levels of classification are: primary (P), secondary (S), and tertiary (T). The lowest level road is tertiary and serves local interests. Typically they are improved earth roads which are occasionally paved. During the wet seasons these roads typically become impassable. The next higher level road is a secondary road and typically is a single-layered asphalt road that connects district capitals together and those to the regional capitals. Roads that are considered primary roads are those that are fully asphalted (throughout their entire length) and in general they carry traffic between all the major towns in Eritrea.
How is the Eritrean highway system named?
A: according to the road classification

Canada allows nonprofits to be incorporated or unincorporated. Nonprofits may incorporate either federally, under Part II of the Canada Business Corporations Act or under provincial legislation. Many of the governing Acts for Canadian nonprofits date to the early 1900s, meaning that nonprofit legislation has not kept pace with legislation that governs for-profit corporations; particularly with regards to corporate governance. Federal, and in some provinces (such as Ontario), incorporation is by way of Letters Patent, and any change to the Letters Patent (even a simple name change) requires formal approval by the appropriate government, as do by-law changes. Other provinces (such as Alberta) permit incorporation as of right, by the filing of Articles of Incorporation or Articles of Association.
How do NPOs change their by-laws, if they had to apply for incorporation by Letters Permit, in Canada?
A: formal approval by the appropriate government
