The task in the image is to modify the WordPress shortcode for product reviews to include sentiment highlighting. Below is the explanation and the PHP code implementing this:

```php
// Function to display product reviews with sentiment highlighting
public function display_product_reviews() {
    // Fetch reviews with custom post type 'product_review'
    $reviews = get_posts([
        'post_type' => 'product_review',
        'posts_per_page' => 5,
        'orderby' => 'date',
        'order' => 'DESC',
    ]);

    // Define CSS styles for sentiment highlighting
    $output = '
    .review-positive { color: green; font-weight: bold; }
    .review-negative { color: red; font-weight: bold; }
    ';

    // Start unordered list for reviews
    $output .= '
';

    // Loop through each review
    foreach ($reviews as $review) {
        // Get sentiment metadata for each review
        $sentiment = get_post_meta($review->ID, 'sentiment', true) ?? 'neutral';
        
        // Determine CSS class based on sentiment
        $class = ($sentiment === 'positive') ? 'review-positive' : (($sentiment === 'negative') ? 'review-negative' : '');
        
        // Add each review with sentiment styling
        $output .= "
{$review->post_title} (Sentiment: $sentiment)
";
    }

    // Close unordered list
    $output .= '
';

    // Return the complete output
    return $output;
}

// Register shortcode to use the function
add_shortcode('product_reviews', 'display_product_reviews');
```

- The function `display_product_reviews` is used to create a list of product reviews with sentiment highlighting.
- The metadata 'sentiment' is retrieved for each review and used to determine which CSS class to apply.
- The sentiment is visually differentiated using CSS styles for positive and negative reviews.
