Premise 1: An abstract knowledge of science seldom useful for the decisions that adults typically make in their daily lives.
Premise 2: Skills taught in secondary school should be useful for making daily lives decisions
Conclusion: Therefore, secondary school science courses should teach students to ''evaluate science-based arguments regarding practical issues'', instead of or perhaps in addition to teaching more abstract aspects of science.
(A) Secondary schools should teach only those skills that are the most useful for the decisions that adults typically make in their daily lives.
Conclusion says ''instead of or perhaps in addition'', so option doesn't work. Moreover argument only mentions ''should be useful. Nothing about the degree of usefulness has been mentioned. NOT THE NECESSARY ASSUMPTION.
(B) Teaching secondary school students the more abstract aspects of science is at least as important as teaching them to evaluate science-based arguments regarding practical issues.
Level of importance hasn't been talked about. Maybe, abstract aspects are unimportant, and we still can draw the conclusion. Just the ''usefulness in daily lives'' should be our concern.
(C) Adults who have an abstract knowledge of science are no better at evaluating science-based arguments regarding practical issues than are adults who have no knowledge of science at all.
Negating this choice is actually in line with the PREMISE:1, which says, ''abstract knowledge'' SELDOM useful. Hence, not necessary for the argument.
(D) No secondary school science courses currently teach students how to evaluate science-based arguments regarding practical issues.
So what? Stimulus says ''what should be'' the case. Shouldn't be concerned about the reality.
(E) The ability to evaluate science-based arguments regarding practical issues is sometimes useful in making the decisions that adults typically make in their daily lives.
Stimulus goes from making daily life decisions to ''evaluate science based arguments''. The option bridges the GAP.
