Remember that footprints and mudcracks tell you whether rocks are right-side up or upside-down, so look for those. Also, if a layer is upside-down, so are the layers that are in the same sedimentary pile, until you hit an unconformity. So, if you have layers Q, R, S and T in one sedimentary pile beneath an unconformity, and then layer U above the unconformity, and you learn that Q is upside-down, so are R, S, and T, but you must look for more information to tell which way is up for U. Referring to the rocks you see here

The great scientist alfred wegener proposed that continents have moved, while other scientists such as t. c.chamberlin argued against wegener. wegener's ideas eventually won, and are now widely accepted, because: a) wegener's ideas were more beautiful, and so were favored by the intellectual elite. b) wegener's ideas did a better job of predicting the results of new observations and experiments. c) wegener's ideas appealed to dead white european males, whereas chamberlin's didn't. d) wegener's ideas appalled dead white european males, and we all know that in this politically correct era, dead white european males cannot get a fair shake. e) wegener won the nobel prize.
