How to Display Just One Post on a Page of Posts

That article is about showing posts from a single category. My template already does that. I desire to show ONE POST only on the page.

Thanks Adity. But the addition of that parameter (argument) made no difference. The page still displays all the posts. Any other ideas?

By the way, the parenthesis is there, just on the next line.

I found an article that gave the fix for the problem noted above.

I had the line indicated. But it had “paged” instead of “page.” With that correction the “Older Posts” link works.

My modified template files is as follows:

<?php
/**
 * Template Name: Page of Posts
 *
 * for a child theme of Twenty_Twelve
 */

get_header(); ?>

	<div id="primary" class="site-content">
		<div id="content" role="main">

		<?php
			$paged = (get_query_var('page')) ? get_query_var('page') : 1;
			$args= array(
				'category_name' => 'news', // Change this category SLUG to suit your use; or see for query parameters http://codex.wordpress.org/Class_Reference/WP_Query#Parameters
				'paged' => $paged,
                     'posts_per_page' => '1');
			query_posts($args);
			if( have_posts() ) :?>

			<?php while ( have_posts() ) : the_post(); ?>
				<?php get_template_part( 'content', get_post_format() ); ?>
				<?php comments_template( '', true ); ?>
			<?php endwhile; // end of the loop. ?>

			<?php twentytwelve_content_nav( 'nav-below' ); ?>

			<?php else : ?>
			<article id="post-0" class="post no-results not-found">
				<header class="entry-header">
					<h1 class="entry-title"><?php _e( 'Nothing Found', 'twentytwelve' ); ?></h1>
				</header>
				<div class="entry-content">
					<p><?php _e( 'Apologies, but no results were found. Perhaps searching will help find a related post.', 'twentytwelve' ); ?></p>
					<?php get_search_form(); ?>
				</div><!-- .entry-content -->
			</article><!-- #post-0 -->

			<?php endif; wp_reset_query(); ?>

		</div><!-- #content -->
	</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
