Question : Comprehension:
Read the following passage and answer the questions given after it.
From January 28 to February 4, 2023, a Chinese-operated, large white high-altitude balloon was seen in North American airspace, including Alaska, western Canada, and the contiguous United States. The American and Canadian militaries asserted that the balloon was for surveillance, while the Chinese government maintained it was a civilian meteorological research airship that had been blown off course. Analysts said that the balloon's flight path and structural characteristics made it dissimilar from those which have typically been used for meteorological research. The U.S. Department of State said that the balloon was capable of locating electronic communication devices, including mobile phones and radios, and that
American U-2 reconnaissance aircraft deployed to track the balloon in the air revealed that the balloon carried antennas and other equipment "clearly for intelligence surveillance and inconsistent with the equipment on board weather balloons." The State Department said that the spy balloon was part of a global Chinese military-directed surveillance effort in which Chinese spy balloons have flown over more than 40 nations in five continents.
On February 4, the U.S. Air Force shot down the balloon over U.S. territorial waters off the coast of South Carolina, on the order of U.S. President Joe Biden. Debris from the wreckage was recovered and sent to the FBI Laboratory in Quantico, Virginia, for analysis.
The incident increased U.S.-China tensions. The incident prompted U.S. Secretary of State Antony Blinken to delay a diplomatic visit to Beijing, which was set to be his first since 2018. It also further strained Canada-China relations, as Canada summoned the Chinese ambassador because of the violation of Canadian airspace. On February 3, the U.S. Department of Defense announced that a second Chinese balloon was passing over Latin America, which China also said belonged to it. On February 10, the Air Force shot down another aerial object over U.S. territory at the order of President Biden.
Question:
How did the US make sure that the Balloon flying over its territory was a 'spy' balloon?
Option 1: the FBI lab confirmed that it was a spy balloon
Option 2: the analysts studied its flight path and said so
Option 3: it's reconnaissance aircraft saw the antennas and equipment of the balloon
Option 4: it got the samples of the balloon checked in a lab
Correct Answer: it's reconnaissance aircraft saw the antennas and equipment of the balloon
Solution : The correct choice is the third option.
Explanation:
The passage mentions that American U-2 reconnaissance aircraft deployed to track the balloon in the air revealed that the balloon carried antennas and other equipment
