Step 1: Identify the verb in the sentence
\[\begin{array}{rl} \bullet & \text{The main verb in the sentence is "is".} \\ \bullet & \text{The phrase "to grow" appears after the word "free" and is in its base form.} \\ \end{array}\]
Step 2: Confirm if "to grow" is an infinitive
\[\begin{array}{rl} \bullet & \text{Since "to grow" consists of "to" + "grow" (the base form of the verb), it is an infinitive.} \\ \bullet & \text{It functions as an adverb, modifying "free" by explaining the purpose of freedom.} \\ \end{array}\]
Final Answer: The infinitive in the sentence is "to grow".
Write the collocations for the following:
(a) ticket \(\underline{\hspace{3cm}}\)
(b) \(\underline{\hspace{3cm}}\) drizzle.
In the following figure \(\triangle\) ABC, B-D-C and BD = 7, BC = 20, then find \(\frac{A(\triangle ABD)}{A(\triangle ABC)}\). 
The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\)) 
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
