According to the research by Edinburgh University, birds have begun to reach their summer breeding grounds on average about one day earlier per degree of increasing global temperatures. It is likely to benefit scientists in terms of predicting how different species may respond to future environmental change, and the study looks at hundreds of species across five continents. Reaching their summer breeding grounds at the wrong time - even by a few days - may cause birds to miss out on maximum availability of vital resources such as food and nesting places. Late arrival to breeding grounds may, in turn, affect the timing of offspring hatching and their chances of survival. Besides, long-distance migrants, which are shown to be less responsive to rising temperatures, may suffer most as other birds gain advantage by arriving at breeding grounds ahead of them. Concisely, the study examines how various species, which take flight in response to cues such as changing seasonal temperatures and food availability, have altered their behaviour over time and with increasing temperatures.

•  According to the text, the study regarding the birds ----.

Developing a brand new rocket, aerospace Rocket Lab has finally transported a finished vehicle to New Zealand launch pad where it will take first flight. ---- Compared to other major missiles like the Falcon 9 or the Atlas V, it is pretty small and light because it was designed specifically to launch small satellites. That’s a relatively light lift contrasted with the others. But Rocket Lab isn’t interested in competing with major players like SpaceX or the United Launch Alliance. The company wants to capitalize solely on what is called the small satellite revolution, a trend of making space probes as tiny as possible.

(I) A new space probe has recently been launched to observe the unknown dark planet Pluto. (II) The expenditure of these project was covered by International Space Association. (III) Though the probe will travel faster than a bullet, it will take about six years to reach Pluto. (IV) Then we will have the first pictures of the planet and extensive information about its atmosphere. (V) It will remain in the orbit for about three years and continue sending information about the structure of the planet’s atmosphere.

(I) People are very interested in the future because they are sure that it will be very different from the past. (II) However, nobody knows how the world will look like in the future. (III) Some say that the progress in science and technology will make life more comfortable and machines will do the hard work for human beings. (IV) There might have been special robots for everybody and people would program them according to their needs. (V) Others speculate that the earth will be very crowded and people from our planet will have to live in space

A Yale University study suggests there are more trees in the world than previously estimated. Billions of trees are being cut down every year - estimated three trillion trees left on Earth. Although it’s more than the previous estimate of 400 billion trees worldwide, it’s trillions less than there used to be. A researcher team used tree density information from forests around the world along with satellite imagery and super-computer technology to map tree populations worldwide at the squarekilometer level. The results were much higher than expected. According to the research, the highest densities of trees are found in the boreal forests in the sub-arctic regions of Russia, Scandinavia and North America, but the largest forest areas are in the tropics, which are home to about 43 percent of the world's trees population. The information on the population of trees will help scientists to better understand the effects of climate change, the distribution of animal and plant species in the world and how trees shape their environments

• According to the passage, besides tree density information, ----.
