The correct answer is A summary lead. To determine this, you can break down the question and analyze each option. A narrative lead typically sets the scene and tells a story, so it's not focused on summarizing information in a concise manner. A staccato lead is a style of writing that uses short and fragmented sentences, so it's not specifically related to summarizing information. A contrast lead would involve comparing and contrasting different elements, which is not what we're looking for here. Therefore, the best option is a summary lead, which is a concise and informative lead that provides an overview of the main information in a limited number of words.
