A speech in which you began by discussing the percentage of drivers during a particular period of time who were drunk when involved in car accidents and then discussed number of deaths each year attributed directly to driving under the influence of alcohol, would be using which organizational pattern?

- Cause-and-effect.

Explanation:

Organizational structure is associated with the author's sequencing of ideas in a specific manner(spatial, chronological, compare and contrast, the order of significance, etc.) to serve the intended purpose and achieve the desired goals.

As per the given description, the author employs 'the cause and effect' organizational structure as it describes that how 'drunken driving or driving under influence' has significantly caused the 'car accidents' and led to the effect of 'the number of deaths each year due to direct involvement of these drunken drivers.' This cause and effect structure assists in explaining the ideas more clearly and promote comprehensive understanding among the readers.
