The scenario in which a scientist who is studying earthquakes includes the impact of wind when performing some tests of damages to structures is an example of failing to hold all other things constant.
In every research and experiment, there are variables that are held constant in order to see how another variables influence the result of the experiment.

This is what i found on google “eightin 1997, the mccaughey septuplets were born in carlisle, iowa. multiple births of as many as eight babies have been born alive, the first set on record to the chukwu family in texas in 1998; one died and seven survived. in 2009, a second set, the suleman octuplets, were born in bellflower, california.” i was surprised about this . i don’t want to have that many babies .
