Um..... no one can answer this.... because we didn't read the story.... but my answer is: He might not have seen his dad in a long time and he was scared to see him again. Or: He is just afraid. Sorry if this does not help.
What sculpture are you talking about ;-;
The choices can be found elsewhere and as follows:
<span>Intaglio printing
relief printing
lithography
</span>
I
think the correct answer from the choices is the first option. Of all
the primary printmaking methods, Intaglio printing is the one that <span>allows the artist the greatest spontaneity and freedom.
