Question

most geologists dismissed alfred wegeners doctrine of continental drift because ______. a they were afraid of a new idea b wegener used several different types of evidence to support his hypothesis c wegener was interested in what earth was like millions of years ago d wegener could not identify a force that could move the continents

Explanation:

Alfred Wegener proposed the continental drift theory but couldn't identify a force (like plate tectonics which was discovered later) to move continents. Geologists at that time dismissed it mainly due to this lack of a force - related explanation. Option a is too simplistic (not just fear of new idea). Option b (using multiple evidences) was actually a positive for his theory but not the reason for dismissal. Option c (interest in Earth's past) is irrelevant to the dismissal reason.

Answer:

d. Wegener could not identify a force that could move the continents
