The figure shows a sample answer grid for question number one hundred one. Option (A) shows the sample answer grid that has a true and a false bubble option for the Roman numeral I statement, a true and false bubble option for the Roman numeral II statement, and a single bubble option for C E. For the Roman numeral I statement the true bubble is filled in, for the Roman numeral II statement the true bubble is filled in, and the C E bubble is filled in.

Correct Answer: 
Yes

In the activity series, text Zn end text is relatively easy to oxidize
to text Zn end text text end text to the power of 2 plus end exponent, while text Cu end text is relatively inactive. Therefore, if text Zn end text metal were placed in a solution containing text Cu end text text end text to the power of 2 plus end exponent ions, text Zn end text would be oxidized to text Zn end text text end text to the power of 2 plus end exponent ions and text Cu end text text end text to the power of 2 plus end exponent would be reduced to text Cu end text metal. Both statements are true, and statement II gives the reason that statement I is correct. The correct answer is therefore true, true, correct explanation.
