Recent research has shown that when calculators are allowed into classrooms at the elementary level, the arithmetic ability of pupils becomes weaker. The calculator is a convenient tool that increases accuracy and is widely used. The use of calculators in school should be limited to high school students. Developmental psychologists have proven that even though a child may seem to grasp a concept fully, that child needs time and practice to integrate it properly if it is to be used as an actual application.

Which of the following, if true, supports the argument's conclusion?

A) Subject matter in the high school syllabus is aimed at developing reasoning and problem-solving logic, and begins to move away from the rudimentary performing of tasks.

B) The systematic approach that working with a calculator demands can assist elementary pupils further in understanding arithmetic method.

C) The functionality of calculators is constantly being improved to include features that apply to a variety of study fields.

D) Almost 75% of the calculators used by elementary school pupils are bought by parents, not by request of their children.

E) In the professional world, many careless errors are committed that could have been prevented if calculators were used.

The calculator is a convenient tool but should be limited to high school students.
Even though a child may seem to grasp a concept fully, that child needs time and practice to integrate it properly.
(This is not the case of high schools where are not concentrating on mere calculations and aimed at logic and concepts. So they are permitted to use calculators)

Which of the following, if true, supports the argument's conclusion?

A) Subject matter in the high school syllabus is aimed at developing reasoning and problem-solving logic, and begins to move away from the rudimentary performing of tasks.(This is inline with our pre-line thinking and the correct answer.)
B) The systematic approach that working with a calculator demands can assist elementary pupils further in understanding arithmetic method.(Weakener-opposite)
C) The functionality of calculators is constantly being improved to include features that apply to a variety of study fields.(OFS)
D) Almost 75% of the calculators used by elementary school pupils are bought by parents, not by request of their children.(OFS)
E) In the professional world, many careless errors are committed that could have been prevented if calculators were used.
(OFS---too broad. this refers whole professional world instead of kids)

Official Explanation



To solve this Conclusion Strengthening question, first break down the argument. The first two sentences are premises which provide factual data; the third sentence includes a recommendation word (should) so it's the conclusion; finally, the fourth sentence cites findings (have proven) so it's a premise:

Premise A: When elementary pupils are given calculators their math becomes weaker
+
Premise B: the calculator is a useful tool
+
Premise C: children can learn about ideas but they also need to practice them
=
Conclusion: calculators should be used by high-school students only

Possible assumption: calculators cannot weaken the learning process of high school students

Strengthening Data: ?

You are required to find data that supports the statement that calculators should only be allowed in high school. The correct answer could be one that confirms the argument's assumption.

This answer choice confirms the argument's assumption by stating that in high school, more focus is put on logic and less on the rudimentary performing of tasks, so a calculator cannot detract from the learning process.

Answer: A
