Next week in America,NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory(SDO),which will take images of the Sun that are 10 times clearer than the most advanced televisions available.

　　The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of thesolar flares(太阳耀斑) and explosions as they occur.

　　Professor Richard Holdaway,the lab’s director,said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth. “If we have advance warning,we’ll be able to reduce the damage. What you don’t want is things switching off for a week with no idea of what’s caused the problem,” he said.

　　1. The phrase “communications blackout” in Paragraph 1 most probably refers to　during the 2016 Olympics.　

　　A. the extinguishing of the Olympic torch

　　B. the collapse of broadcasting systems

　　C. the transportation breakdown in London

　　D. the destruction of weather satellites

　　2. What can be inferred about the solar activity described in the passage?
