📗 [1 points] (SU23M2Q1, S23M2Q1) Given that driver is a Selenium WebDriver, which of the following enables us to find all the table elements within a web page?

driver.find_elements("tag name", "table")
driver.find_elements("tag name", "td")
driver.find_elements("name", "table")
driver.find_elements("name", "td")

📗 [1 points] (SU23M2Q3, S22M2Q2, F21MQ2) The Document Object Model (DOM) for a web page may not be which of the following data structure?

binary tree
weakly connected graph
directed acyclic graph
tree

📗 [1 points] (SU23M2Q2, SU23FQ11) Assume element is a Selenium WebElement given by <a href="page.html" target="_blank">link<\a>. Which of the following returns link?

element.text
element.get_attribute("text")
element.get_attribute("href")
element.href

📗 [1 points] (S23M2Q2) Assume that the variable text stores a reference to a WebElement object instance which can accept input. Which of the following will enable us to send 1 as the input?

text.send_keys("1")
text.send_keys(1)
text.send_key("1")
text.send_key(1)

📗 [1 points] (S23FQ29) Given the following HTML snippet:

<div id="a">
<ul>
<li>1</li>
<li>2</li>
</ul>
</div>
<div id="b">
<ul>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
</div>

Assuming driver is correctly initialized, what does the following code snippet print?

element = driver.find_element("id", "a")
elements = element.find_elements("tag name", "li")
print(len(elements))

📗 [1 points] (new) Which one of the following methods is guaranteed to find a goal node that is 5 edges away from the initial node in a graph? Assume each node has a finite number of children.

📗 [1 points] (new) Suppose the following nodes are in the priority queue, {node: "A", g: 1, h: 10}, {node: "B", g: 3, h: 7}, {node: "C", g: 5, h: 3}, {node: "D", g: 7, h: 2}, where "g" represents the distance from the initial node and "h" represents the heuristic (estimated distance to the goal node).

"A"
"B"
"C"
