Problem: Originally, the hardware architecture was so closely tied to the Mac OS operating system that it was impossible to boot an alternative operating system. The most common workaround, is to boot into Mac OS and then to hand over control to a Mac OS-based bootloader application. Used even by Apple for A/UX and MkLinux, this technique is no longer necessary since the introduction of Open Firmware-based PCI Macs, though it was formerly used for convenience on many Old World ROM systems due to bugs in the firmware implementation.[citation needed] Now, Mac hardware boots directly from Open Firmware in most PowerPC-based Macs or EFI in all Intel-based Macs.
What were Open Firmware-based PCI Macs used as a convenience because of?
---
Answer: bugs in the firmware implementation


Problem: In October 1810, six months after Fryderyk's birth, the family moved to Warsaw, where his father acquired a post teaching French at the Warsaw Lyceum, then housed in the Saxon Palace.

Chopin was of slight build, and even in early childhood was prone to illnesses.
What instrument did Chopin's mother teach?

Answer: piano


Problem: A scientific study in the journal, Biological Conservation, states that trophy hunting is of "major importance to conservation in Africa by creating economic incentives for conservation over vast areas, including areas which may be unsuitable for alternative wildlife-based land uses such as photographic ecotourism." However, another study states that less than 3% of a trophy hunters' expenditures reach the local level, meaning that the economic incentive and benefit is "minimal, particularly when we consider the vast areas of land that hunting concessions occupy."
What did another study show that less than 3% of reached the local level?
---
Answer:
expenditures
