Answer:
D). Two sizes of bullet points distinguish between two levels of information.
Step-by-step explanation:
The above statement correctly describes the use of text feature i.e. 'two distinct sizes of bullet points to differentiate the two varying degrees of the information' that he/she provides. Firstly, the bullet point is employed to denote the 'to-do list' while preparing for a long car trip like getting your car tuned up, keeping a spare tire, etc. While the smaller size of bullet points used later is to mark the list of items that an 'emergency car kit' must include like a flashlight, flares, jumping cables, etc.
Thus, the use of two distinct sizes of bullet points displays two levels of description(first is of the list of things that one should consider prior to a long trip and the second is the series of items an emergency car kit must contain).
