The code is missing an import statement for the requests library, which is required to retrieve the HTML content. Here's the updated code with the necessary import statement:

import requests
from bs4 import BeautifulSoup

def retrieve_paragraphs_by_title(url):
    response = requests.get(url)
    html = response.content
    soup = BeautifulSoup(html, 'html.parser')

    paragraphs = []
    for title in soup.find_all(['h1', 'h2', 'h3', 'h4', 'h5', 'h6']):
        paragraph_text = ''
        for sibling in title.find_next_siblings():
            if sibling.name.startswith('h'):
                break
            elif sibling.name == 'p':
                paragraph_text += sibling.get_text()
        paragraphs.append((title.get_text(), paragraph_text.strip()))

    return paragraphs

This code uses the requests.get() function to retrieve the HTML content from the specified URL. It then passes the content to BeautifulSoup for parsing. The rest of the code remains unchanged
