Here is the item:
Juan herd his mother calling from down the
street but chose to ignore
her summons. Although he knew
that she would be angry about his late arrival for dinner, he had to finish
his inspection of the dead toad on the sidewalk.
The first verb, herd, is the problem. As you know, the sentence requires the simple past. Heard is the correctly spelled form.
