2. Using computer labs to ------- classroom instruction is most effective when the curriculum ------ lab exercises and classroom teaching in a coordinated manner.

A. supplement… integrates
B. substantiate… undermines
C. remedy… compromises
D. disparage… reinforces
E. foster… curtails

Correct Answer: A

Explanation:

Explanation for Correct Answer A :

Choice (A) is correct. "Supplement" means to add extra material to something, and "integrate" in this context means to bring parts together into a whole unit. If one were to insert these terms into the text, the sentence would read "Using computer labs to supplement classroom instruction is most effective when the curriculum integrates lab exercises and classroom teaching in a coordinated manner." Computer labs are treated in this sentence as extra material that is brought into the curriculum, and that process would naturally be most effective if computer labs were brought together with classroom instruction in a unified way.

Explanation for Incorrect Answer B :

Choice (B) is incorrect. "Substantiate" means to show something to be true by giving evidence for it, and "undermine" in this context means to destroy the support for something. If one were to insert these terms into the text, the sentence would read "Using computer labs to substantiate classroom instruction is most effective when the curriculum undermines lab exercises and classroom teaching in a coordinated manner."A study plan that destroys the support for both lab exercises and classroom teaching cannot be effective, especially since those are the only instructional methods that seem to be in use in this situation.

Explanation for Incorrect Answer C :

Choice (C) is incorrect. "Remedy" means to fix, and "compromise" in this context means to place the success of something in danger. If one were to insert these terms into the text, the sentence would read "Using computer labs to remedy classroom instruction is most effective when the curriculum compromises lab exercises and classroom teaching in a coordinated manner." Any curriculum that would put the success of both lab instruction and classroom teaching in danger is almost certain to fail, and it cannot be reasonably called an effective way to remedy, or fix, classroom instruction.

Explanation for Incorrect Answer D :

Choice (D) is incorrect. "Disparage" means to make negative comments about, and "reinforce" means to strengthen. If one were to insert these terms into the text, the sentence would read "Using computer labs to disparage classroom instruction is most effective when the curriculum reinforces lab exercises and classroom teaching in a coordinated manner." Using computer labs to make negative comments about classroom instruction is an odd idea, and it is unclear why any serious educator would want to try it. In any case, there is no reason to believe that such an activity would be most effective when the curriculum strengthens both lab exercises and classroom teaching. Those conditions would most likely weaken any attempt to disparage classroom instruction.

Explanation for Incorrect Answer E :

Choice (E) is incorrect. "Foster" in this context means to promote, and "curtail" means to cut short. If one were to insert these terms into the text, the sentence would read "Using computer labs to foster classroom instruction is most effective when the curriculum curtails lab exercises and classroom teaching in a coordinated manner." If the curriculum cuts both lab exercises and classroom teaching short, it is very unlikely that using computer labs to promote classroom instruction will be effective.
