Thanks Joy for the suggestion. This is what I had done for now, i.e.
.post-content > p {
text-align: left;
}

However, I also have <p align=”center”> and sometimes <p align=”right”> in my HTML file. My code looks like this

<div class="main-container">
	<article id="page-205" class="post-205 page type-page status-publish hentry">
		<header class="post-header">
		<h1 class="page-title">Title</h1>	</header>
			<div class="post-content">
<h2 align="center">Title</h2>
<p align="center">By</p>
<h3 align="center">Author</a>
<p align="left"><i>These twenty ...</i></p>
<p align="center"><b>1. Instruction</b></p>
<p align="left">Text.</p>
<p align="center"><b>2. Method</b></p>
<p align="left">Text.</p>
....

The different alignments are residing within the same post-content class. I shall talk to the author.
