Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
Section I of the exam consists of four-option multiple choice questions; the total number varies each year. The first half of the section is listening-based; the proctor will begin playing a provided CD, and the exam will begin. Each question or group of questions is based on a musical selection or an auditory stimulus.
50 multiple-choice questions – 60 minutes total 25 mathematics, science and technology multiple-choice questions – 30 minutes; 25 arts and humanities multiple-choice questions – 30 minutes; Note: Time for each part are suggestions only. Students are free to spend more or less time on any other parts in Section B.
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]
A sonority hierarchy or sonority scale is a hierarchical ranking of speech sounds (or phones).Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, [1] therefore sonority is often related to rankings for phones to their amplitude.

The fraction of sound absorbed is governed by the acoustic impedances of both media and is a function of frequency and the incident angle. [2] Size and shape can influence the sound wave's behavior if they interact with its wavelength, giving rise to wave phenomena such as standing waves and diffraction .
A sound wave propagates through a material as a localized pressure change. Increasing the pressure of a gas or fluid increases its local temperature. The local speed of sound in a compressible material increases with temperature; as a result, the wave travels faster during the high pressure phase of the oscillation than during the lower pressure phase.
