Look at this reading. Those two questions are tricky. What do you think.
Weather forecasting is the use of science and technology to predict the state of the atmosphere for a given location. Human beings have tried to predict the weather informally for thousands of years, and formally since the nineteenth century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere on a given place and using scientific understanding of atmospheric processes to predict how the atmosphere will be on that place.Once an all-human endeavor based mainly upon changes in barometric pressure, current weather conditions, and sky condition, weather forecasting now relies on computer-based models that considers atmospheric factors. Human input is still required to select the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The ever-changing nature of the atmosphere, the great computational power required to solve the equations that describe the atmosphere, error involved in measuring the initial conditions, and an incomplete understanding ofatmospheric processes mean that forecasts become less accurate as the difference in current time and the time for which the forecast is being made increases.
1. According to the passage, weather forecasting ------------.
1) is a new technology
2) has a long history
3) began less than 100 years ago
4) is not as effective as it used to be
2. The passage is mainly concerned with ---------------.
1) the reasons why humans are attracted to weather forecasting
2) the circumstances under which weathermen make mistakes
3) a definition of weather forecasting and the way it is done
4) the early methods used to predict weather conditions
My answers: 1. 2 (To me, #4 would work as well.)
2. 3
