Part A Directions: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. In the late summer of 2005, the remarkable flooding brought by Hurricane Katrina, which caused more than $ 200 billion in losses, was the worst natural disaster in U.S. history. However, even in typical years, flooding causes billions of dollars in damage and threatens lives and property in every State. Natural processes, such as hurricanes and weather systems can cause floods. Failure of levees and dams and inadequate drainage in urban areas can also result in flooding. On average, floods kill about 140 people each year and cause $ 6 billion in property damage. Although loss of life to floods during the past half-century has declined, mostly because of improved warning systems, economic losses have continued to rise due to increased urbanization and coastal development. Flooding happens during heavy rains, when rivers overflow, when ocean waves come onshore, when snow melts too fast or when dams or levees break. Flooding may be only a few inches of water or it may cover a house to the rooftop. Floods that happen very quickly are called flashfloods. Flooding is the most common of all natural hazards. It can happen in every U. S. state and territory. And here is something else for you: -Flood Watch or Flashflood Watch--Flooding may happen soon. Stay tuned to the radio or television news for more information. If you hear a flashflood warning, talk to an adult immediately! -Flood Warning--You may be asked to leave the area. A flood may be happening or will be very soon. Tell an adult if you hear a flood warning. If you have to leave the area, remember to bring your Disaster Supply Kit and make arrangements for your pets. -Flashflood Warning--A flashflood is happening. Get to high ground right away. Tell an adult! What can be inferred about the flooding problem in U. S. from the passage?
A.
The tragedy happening in 2005 is an exception from a country that barely witness floods so frequently.
B.
Flood is not such a serious problem as hurricanes and other forms of natural disasters in U. S..
C.
That is an extreme example to represent the serious problem of flood U. S. has been faced with for many years.
D.
The example in 2005 is typical, just like any other year in U. S..
