I'm taking a test and have to guess the right answer to the question after the article. Article: We have known for a long time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at particular times. It is not as simple as we might think, as new experiments have shown. In one experiment, flowers were kept in darkness. We might expect that the flowers, without any information about the time of the day, did not open as they usually do. In fact, they continued to open at their usual time. This shows that they have some mysterious way of knowing the time. Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of "inner clock". This discovery may not seem to be very important. However, it was later found that not just plants but also animals including man have this "inner clock"which controls working of their bodies and their activities. Human beings, then, are also controlled by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food. And our ability to concentrate . Question: That flowers have the sense of time is related to _ . Options: A: sunlight B: weak light C: the "inner clock" D: the information from the outside world

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: A new product - the Apple Watch - into the market. Last year, the watch was firstly introduced by Tim Cook, Apple's CEO. The price of the watch is from $349 to $1,099, depending on its size and whether it is a sports or regular one. Apple engineers and designers have put in a lot of thought and hard work into creating this "small screen" on your wrist .

You can s end personal messages to your friend --such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist. Besides telling the time, the watch will use 'Bluetooth' to connect with your iPhone and show calls or text messages that come in. According to Tim Cook, the watch may open up a whole new area of applications that we had never thought of. Some car f actories like BMW have developed an app that allows its car owners to open their cars with the watch.
