In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: When a caterpillar feeds on a tomato leaf , the plant moves rapidly to meet with a defensive response , systematically releasing " proteinase inhibitors " -- proteins that interfere with the caterpillar's digestion -- throughout the plant , especially in the leaves . But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved . "
Answer: They cure diseases by changing chemicals
Example Output: What is the function of the " proteinase inhibitors " in tomato plants ?

Example Input: Article: If you're looking for the place that has everything, there's only one place to visit, and that's New York. It's a whole world in a city. The World of Theatre: All of New York is a stage. And it begins with Broadway. Where else can you find so many hit shows in one place? Only in New York! The World of Music: Spend an evening with Beethoven at Lincoln Center. Swing to the great jazz of Greenwich Village. Or rock yourself silly at the hottest dance sports found anywhere. The World of Art: From Rembrandt to Picasso. From Egyptian tombs to Indian teepees. Whatever kind of art you like, you'll find it in New York. The World of Fine Dining: Whether it's a roast Beijing duck in Chinatown, lasagna in Little Italy, or the finest French coqauvin found anywhere, there's a world of great taste waiting for you in New York. The World of Sights: What other city has a Statue of Liberty ? A Rockefeller Center? Or a Bronx Zoo? Where else can you take a horse-drawn carriage through Central Park? Only in New York!
Answer: To see the Statue of Liberty.
Example Output: Which of the following programmes can a visitor have only in New York?
