Barbara, a wealthy widow, promises the pastor of her church that she will donate $30,000 to the church to help pay off its mortgage if the stewardship committee can obtain enough pledges for the balance of the $60,000 mortgage. Other pledges are obtained to pay off the mortgage, but now Barbara has changed her mind and plans to take an around-the-world cruise instead. In this case: A) Barbara's promise to pay $30,000 is enforceable because it was a promise made to satisfy a preexisting moral obligation.
B) the promise to pay $30,000 is a promise to give a gift and is therefore not enforceable.
C) under the Restatement of Contracts, Barbara's promise is enforceable.
D) Two of the above, (a) and (c).

Which of the following is true about presentation methods for providing training? audiovisual techniques are most effective when they are used alone. mobile technologies include training methods such as on-the-job training, simulations, business games and case studies, behavior modeling, interactive video, and web-based training that require the trainee to be actively involved in learning. the typical users for teleconferencing include employees who are part of a workforce that spends most of its time traveling, visiting customers or various company locations and has limited time available to spend in traditional training activities. webcasting involves classroom instructions that are provided online through live broadcasts. classroom instruction is no longer a popular training method because of new technologies such as interactive video and computer-assisted instruction.
