Final answer:
Elie Wiesel was 15 years old at the time of deportation from Sighet to Auschwitz in 1944, but the exact time since then would depend on the current year. The reference to the Vienna Genesis suggests a mix-up with the Biblical story of Rebecca and Eliezer, unrelated to Elie Wiesel's life.
Step-by-step explanation:
The question appears to be mixing two separate elements. The reference to Elie's residence at Sighet immediately brings to mind Elie Wiesel, the author of 'Night', who was from Sighet, a town which is now part of Romania.
In contrast, the information provided is about an artwork depicting the Biblical story of Rebecca and Eliezer, contained within the Vienna Genesis from the early 6th century, which is unrelated to Elie Wiesel.
This suggests there might be some confusion on the student's part. The Vienna Genesis is an example of Early Christian art, notable for its continuous narrative and symbolic emphasis rather than spatial accuracy.
Assuming the student is referring to Elie Wiesel, it is known that Elie Wiesel was 15 years old when he and his family were deported from Sighet to Auschwitz concentration camp in 1944.
The time that has passed since then would depend on the current year the question is being asked. However, we cannot determine the exact time from Elie's residence at Sighet without the current year being provided.
