  没有明显逻辑的句子简化题

  例题3:Over long periods of time, substances whose physical and chemical properties change with the ambient climate at the time can be deposited in a systematic way to provide a continuous record of changes in those properties overtime, sometimes for hundreds or thousands of years. Information on temperature, rainfall, and other aspects of the climate that can be inferred from the systematic changes in properties is usually referred to as proxy data.

  Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?

  •   Because physical and chemical properties of substances are unchanging, they are useful records of climate fluctuations over time

  •   For hundreds or thousands of years, people have been observing changes in the chemical and physical properties of substances in order to infer climate change

  •   Because it takes long periods of time for the climate to change, systematic changes in the properties of substances are difficult to observe.

  •   Changes in systematically deposited substances that are affected by climate can indicate climate variations over time.
