Task: Question Answering
Input (English): Question: In an evaluation the redox indicator In (ox) + ne-  In (network) is used, whose normal potential is E0. The color change will occur: 
 Options:  <1> To the potential of the equivalence point. <2> To the value of E0. <3> In the interval E0  0.059 / n. <4> In the interval E0 (ox) - E0 (network) if it is evaluated with a reducer. <5> At the potential of 0.059 / n.
Output (English): 3
