instruction:
This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

question:
Passage: Since its inception, the department has had its temporary headquarters in Washington, D.C.'s Nebraska Avenue Complex, a former naval facility. The 38-acre  site, across from American University, has 32 buildings comprising 566,000 square feet  of administrative space. In early 2007, the Department submitted a $4.1 billion plan to Congress to consolidate its 60-plus Washington-area offices into a single headquarters complex at the St. Elizabeths Hospital campus in Anacostia, Southeast Washington, D.C. The earliest DHS would begin moving to St. Elizabeths is 2012. The move is being championed by District of Columbia officials because of the positive economic impact it will have on historically depressed Anacostia. The move has been criticized by historic preservationists, who claim the revitalization plans will destroy dozens of historic buildings on the campus. Community activists have criticized the plans because the facility will remain walled off and have little interaction with the surrounding area.On January 8, 2009, the National Capital Planning Commission approved the Department of Homeland Security's plans to move into the campus of St. Elizabeths Hospital.In February 2015 the General Services Administration said that the site would open in 2021.
answer:

How many acres and buildings does the DHS headquarters in Washington, D.C.'s Nebraska Avenue Complex contain in total?
