Competition for employees with the public and private sector is another problem that Nonprofit organizations will inevitably face, particularly for management positions. There are reports of major talent shortages in the nonprofit sector today regarding newly graduated workers, and NPOs have for too long relegated hiring to a secondary priority, which could be why they find themselves in the position many do. While many established NPO's are well-funded and comparative to their public sector competetitors, many more are independent and must be creative with which incentives they use to attract and maintain vibrant personalities. The initial interest for many is the wage and benefits package, though many who have been questioned after leaving an NPO have reported that it was stressful work environments and implacable work that drove them away.
What is a primary interest to prospective NPO employees?
A: wage and benefits package

The particular contrasts which are phonemic in a language can change over time. At one time, [f] and [v], two sounds that have the same place and manner of articulation and differ in voicing only, were allophones of the same phoneme in English, but later came to belong to separate phonemes. This is one of the main factors of historical change of languages as described in historical linguistics.
What cannot change over time?
A: unanswerable

Finite symmetry groups such as the Mathieu groups are used in coding theory, which is in turn applied in error correction of transmitted data, and in CD players. Another application is differential Galois theory, which characterizes functions having antiderivatives of a prescribed form, giving group-theoretic criteria for when solutions of certain differential equations are well-behaved.u[›] Geometric properties that remain stable under group actions are investigated in (geometric) invariant theory.
What stable properties does the Galois theory study?
A:
unanswerable
