Final answer:
Information on the Geico gecko would be found in the 'Corporate symbols' subsection of the 'In culture' section of an article titled 'Geckos'.
Step-by-step explanation:
In the article titled "Geckos," you would expect to find information about the type of gecko used in commercials for the Geico car insurance company in Section 3, which delves into how geckos are represented in culture. More specifically, under the subsection 3.2 Corporate symbols, you would likely find details regarding the association of geckos with corporate branding and marketing, such as the Geico gecko. This is because the Geico gecko is a prominent example of a corporate symbol, and the article section focusing on cultural representations would be the most appropriate place for such content.
