The present invention provides an apparatus and a method for providing a practical question solving exercise and question solving habit correction using an equipment of an examinee in preparation for a multiple choice test. The first and the second agent may be a biologic, such as an antigen-binding protein, or a small molecular tyrosine kinase inhibitor, for example. The driving frequency for the power supplied to the power supply module is not a resonant frequency in the power supply module and the power receiving module. The method further includes transforming the audio data via a non-linear transformation to produce modified audio data having a second playback rate, modifying the video data to produce modified video data having the second playback rate, and synchronizing the modified audio data and the modified video data to produce modified media content having the second playback rate.
