Example

If all that is desired is to call attention to the fact that the copy text has been corrected, corr may be used alone:

I don't know,
Juan. It's so far in the past now — how <corr>can we</corr> prove
or disprove anyone's theories?
Example

It is also possible, using the choice and sic elements, to provide an uncorrected reading:

I don't know, Juan. It's so far in the past now —
how <choice>
 <sic>we can</sic>
 <corr>can we</corr>
</choice> prove or
disprove anyone's theories?
