Take the works exhibited this year. In order to avoid selecting an artist on the basis of just one good work that might be the exception in a body of poor work, entrants were required to supply ten slides showing previous works in addition to one actual work.
以今年雙年展的參賽作品為例，為了不讓參賽者可能因為一件偶爾為之的好作品而入選，參賽者除了一件代表作，還要附上十張歷來的作品幻燈片。
