Answer:
B. Do a quick vehicle pre-check
Explanation:
Checking your vehicle everyday before driving will prevent you from having any incident which can eventually lead to a traffic accident. Scanning the vehicle includes checking on the conditions of brakes, tyres, mirrors, seatbelts, the horn, steering mechanism, and winshield wipers. Making this inspection a habit is the best way to avoid stressful and dangerous situations.
Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
