Final answer:
Sader gave Sophie a chatelaine watch made of German silver as a gift after the Trial by Tale.
Step-by-step explanation:
After the Trial by Tale, Sader gave Sophie a chatelaine watch made of German silver. This gift was to HER, and not to McTeague, as Marcus Schouler emphasized. The watch is a type of decorative belt hook or clasp that was popular in the 19th century, typically worn on a woman's waist belt and used to hold small items like keys or a watch. It was a thoughtful and elegant gift from Sader to Sophie.
