Read the following article and select the best answer. 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 . " Question: The best title of this passage is   _ - Electrical Tomatoes - Endless Cycles of Plants - A Debatable Research - A Magic Role of Caterpillars
**Answer**

*Question*
Read the following article and select the best answer. Article: There is no doubt that much of the profit of a business--sometimes the whole of its success--depends upon the use of the odds and ends.The odds and ends are various small things,which are left over when the main things are produced.But they possess a real value of their own. If a business,big or small,looked down upon these odds and ends,it would mean a big difference in the amount of the benefit of the business.Take a meat factory for instance, there are countless odds and ends--bones and hair,which can be made into glue and rope to increase its profit greatly. Then,if we are college students,what about our odds and ends--the odd moments? Take time for example.Every one of us has the exact same amount of it.Everyone's success or failure depends on the use of their time.But everyone uses the time more or less in the same way.However,why many great men in science or art have made huge successes for themselves in the world?Because they have made best use of their odd moments.Take Thomas A.Edison, he never allowed his odd moments to slip by.He thought,planned,and tried his inventions.He always worked twenty hours out of each twenty-four.His inventions made him famous all over the world,and provided valuable wealth for the human beings. So, remember this axiom:very busy people always find time for everything.However,people with great spare time find time for nothing.Is it very strange?Not at all!The question is how to gather up fragments of time and make full use of them.As many big businesses have found,that the real profit is in using the odds and ends.We also must do in this way to make best use of our odd moments and manage to be successful in something that we do. Question: Why should the odds and ends be made full use of ?Because    _  . - lots of factors in success or in failure depend on the best use of odds and ends - they control to possess a value of their own - they are various small things people don't want - they are useless things left over when the main things are produced
**Answer**
lots of factors in success or in failure depend on the best use of odds and ends
