Changing full post to excerpt in categories of Twenty Sixteen

I have the Twenty sixteen theme and I want excerpts to be displayed in category pages instead of full posts.
I see that the file archive.php contains the following lines in The Loop:
while ( have_posts() ) : the_post();
get_template_part( ‘template-parts/content’, get_post_format() );
endwhile;

How should I change them to show the excerpts?
I tried replacing the line with the_excerpt(); but titles are not displayed.
Thank you.
