effect
effect
hint: what became of the space shuttle program?

Explanation:

For the "Cause" box (related to Reagan appointing the commission):

The Challenger space shuttle exploded during launch (on January 28, 1986), resulting in the loss of the crew. This tragic event (the disaster itself) was the cause that led President Reagan to appoint a commission to investigate what went wrong.

As stated, the disaster (cause) led to Reagan appointing a commission to investigate. So the effect here is the appointment of the commission to look into the disaster's causes and circumstances.

After the Challenger disaster and the commission's investigation, the space shuttle program was suspended for about 32 months (until September 1988) to implement safety improvements, redesign components (like the solid rocket boosters' O - rings), and enhance quality control and safety protocols. Also, there was a shift in public perception and increased scrutiny of NASA's operations.

Answer:

The Challenger space shuttle disaster (explosion during launch, loss of crew)

For the first "Effect" box (effect of the disaster leading to the commission):
