Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Some paleontologists suggest that animals appeared much earlier than the Cambrian explosion, possibly as early as 1 billion years ago. Trace fossils such as tracks and burrows found in the Tonian period indicate the presence of triploblastic worms, like metazoans, roughly as large (about 5 mm wide) and complex as earthworms. During the beginning of the Tonian period around 1 billion years ago, there was a decrease in Stromatolite diversity, which may indicate the appearance of grazing animals, since stromatolite diversity increased when grazing animals went extinct at the End Permian and End Ordovician extinction events, and decreased shortly after the grazer populations recovered. However the discovery that tracks very similar to these early trace fossils are produced today by the giant single-celled protist Gromia sphaerica casts doubt on their interpretation as evidence of early animal evolution."?

The answer is:
From what era, once thought devoid of animal life, was evidence of grazer populations discovered?

Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "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."?

The answer is:
Nonprofits have issues finding the best what for management jobs?

Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced."?

The answer is:
What is reduced by playback equipment?
