Question

streaking across the sky at seventeen thousand miles an hour, the international space station (iss) is larger than a six - bedroom house and covered with an acre of solar panels. its impressive size and highly reflective surface have the effect of making the iss visible from earth with the naked eye. since the iss is shrouded by earths shadow about thirty percent of the time, viewers can see it only once or twice a night. around the summer and winter solstices, however, the iss is exposed by nearly constant sunlight. this results in the space station being visible as many as five times in one night.
match causes with their effects.
viewers can see the iss up to five times in a single night.
the iss is visible without a telescope.
earths shadow hides the iss.
cause
the iss is huge and shiny.
effect
people can see the iss only one or two times a night.
twice a year, the iss is perpetually lit up by the sun.

Explanation:

• The text states that the ISS's "impressive size and highly reflective surface" (which can be paraphrased as "huge and shiny") make it "visible from Earth with the naked eye" (i.e., "visible without a telescope").
• It also says that when "the ISS is shrouded by Earth's shadow about thirty percent of the time", "viewers can see it only once or twice a night".
• And when "around the summer and winter solstices... the ISS is exposed by nearly constant sunlight", "the space station being visible as many as five times in one night".

Answer:

• Cause: The ISS is huge and shiny. $\to$ Effect: The ISS is visible without a telescope.
• Cause: Earth's shadow hides the ISS. $\to$ Effect: People can see the ISS only one or two times a night.
• Cause: Twice a year, the ISS is perpetually lit up by the sun. $\to$ Effect: Viewers can see the ISS up to five times in a single night.
