大学入学共通テスト - Independent foundational practice common mistakes
大学入学共通テスト - Independent foundational practice · Understand the traps and how to avoid them.
Treating a qualification as a complete rejection
Words such as だけでは十分ではない limit a claim without necessarily denying its value.
What to do instead
Restate the claim with its limitation before comparing options.
Using a vertex outside the allowed interval
An unrestricted quadratic minimum need not occur in a restricted input set.
What to do instead
Check membership of the vertex and calculate endpoint values.
Keeping the original probability denominator after conditioning
The condition removes some possible outcomes from consideration.
What to do instead
Write the restricted sample space before counting favorable outcomes.
Choosing an option that adds a plausible detail
Plausibility does not establish that a passage contains or supports the detail.
What to do instead
Locate explicit evidence or a necessary inference for every part of the answer.
Assuming kinetic energy is conserved in every collision
An inelastic impact can convert kinetic energy into internal energy.
What to do instead
Select the model and conservation law before calculating.
Ignoring the limiting reactant
Reaction coefficients constrain how much of each substance can react.
What to do instead
Compare available amounts after dividing by stoichiometric coefficients.
Confusing monetary and fiscal actions
The institutions and policy instruments differ.
What to do instead
Identify the decision-maker and the specific action being taken.
Equating correlation with causation
Other variables and selection effects can create an association.
What to do instead
State what the observations show and what additional comparison is needed.
