Pls help 15 points Read the passage below from “The Unseen Values.” However we think of it, it is a dawning period and one which—in its scope and potential—promises to dwarf much of what has gone before. Those who have given careful thought to the matter are convinced that while some caution is in order, the new era is not one to be approached with timidity, inhibited imagination or too much convention. Neither is there any point in trying to hold off the tempo of this oncoming age or, in any other way, to evade it.

To signify the bright future of space exploration
To represent the harsh reality that will soon be evident

To illustrate the enlightenment of scientists in the field
