Answer:
You shouldn't judge the worth or value of something, by its outward appearance alone.
Step-by-step explanation:
In the given passage about Laila and Sarah, the first impression that Sarah had of Leila was to stay away from her because she seemed weird. But with time and communication, that 'stranger' phase changed to being friends.
So, the transition of Sarah before and after she 'knows' Laila shows how one shouldn't judge the worth or value of something based solely on outward appearance. The two girls' relationship from being strangers to 'good friends' shows just how it is never a good thing to make judgments based on the outside appearance, before really looking into the inside of a person or anything.
Thus, the correct answer is the last/fourth option.
