Final answer:
The high winds causing seafoam north of Brisbane indicate the location is Australia. After WWI, Australia also controlled German New Guinea.
Step-by-step explanation:
High winds stirring up a lot of foam on the coast north of Brisbane, Queensland, would be in the country of Australia. Brisbane is a city on the eastern coast of Australia, so the correct answer is b) Australia. The seaside phenomena of foam is common in coastal regions, especially during strong wind events, and Brisbane being on the eastern coast of Australia does experience such weather conditions. When answering the historical question, after World War I, German New Guinea came under the control of Australia, as per the League of Nations mandate. Although this historical point is not directly related to the question about foam on the coast, it provides context to the region's history.
