question:
(CNN) -- Lewis Hamilton extended his Formula One drivers' championship lead after finishing second behind Red Bull's Mark Webber at the British Grand Prix. 

World champion Jenson Button, who narrowly missed out on his first podium finish at Silverstone after coming fourth, still trails McLaren teammate Hamilton in second. 

Third-placed Webber stormed back into title contention after winning his third race of the season. The Australian leapfroged fellow Red Bull driver Sebastian Vettel, who is 24 points adrift of Hamilton in fourth. 

McLaren also lead Red Bull by 29 points at the top of the constructors' championship. 

Ferrari's Fernando Alonso stayed fifth overall but lost ground after earning no points, ending the race in 14th after being given a drive-through penalty for illegally overtaking Robert Kubica of Renault off the track. 

Nico Rosberg of Germany continues to outperform his Mercedes teammate Michael Schumacher, recording his third podium finish this season to replace Kubica in sixth. 

Drivers' Championship (after 10 rounds): 

1. Lewis Hamilton (GB) McLaren 145 points 

2. Jenson Button (GB) McLaren 133 

3. Mark Webber (Aus) Red Bull 128 

4. Sebastian Vettel (Ger) Red Bull 121 

5. Fernando Alonso (Sp) Ferrari 98 

6. Nico Rosberg (Ger) Mercedes GP 90 Constructors' Championship: 

1. McLaren 278 points 

2. Red Bull 249 

3. Ferrari 165 

4. Mercedes GP 126 

5. Renault 89

question:
A bracket is a tall punctuation mark typically used in matched pairs within text, to set apart or interject other text. The matched pair may be described as opening and closing, or left and right symbols. 

Forms include round (also called "parentheses"), square, curly (also called "braces"), and angle brackets (also called "chevrons"); and various other pairs of symbols. 

In addition to referring to the class of all types of brackets, the unqualified word "bracket" is most commonly used to refer to a specific type of bracket: in modern American usage this is usually the square bracket and in modern British usage this is usually the round bracket. 

Chevrons were the earliest type of bracket to appear in written English. Desiderius Erasmus coined the term "lunula" to refer to the rounded parentheses (), recalling the shape of the crescent moon. 

Some of the following names are regional or contextual. 

The characters ‹ › and « », known as guillemets or "angular quote brackets", are actually quotation mark glyphs used in several European languages. Which one of each pair is the opening quote mark and which is the closing quote varies between languages. 

In English, typographers generally prefer to not set brackets in italics, even when the enclosed text is italic. However, in other languages like German, if brackets enclose text in italics, they are usually set in italics too.

What was the first form of brackets in written English?


question:
Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true. 

People who studied plants have found out that plants carry a small electrical charge . It is possible to measure this charge with a small piece of equipment called "galvanometer". The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened. 

A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects . 

Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room. 

Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.
answer:

Are plants known to carry an electrical charge?
