<u>Answers:</u>
1. A way to show affection to someone is to hug that person. In Spanish the verb to hug means <em>abrazar (to surround something or someone with the arms)</em>.
If two or more people <u>hug among them</u>, the verb <em>abrazar</em> is conjugated as <em>abrazarse</em>. Hence, the right answer is B:
<h2>abrazar (se)
</h2>
The other options are incorrect because:
<em>charlar</em> means to talk or chat
<em>llevarse mal </em>means to not get along with someone
<em>despedirse (de)</em> means to say good bye to someone
2. The sentence <em>Elena y Alex se abrazaron</em> means:
Elena and Alex (they) hugged <u>each other</u>.
This means the action of hugging (<em>abrazarse</em>) was <u>reciprocal </u>between the two subjects.
Therefore, the right answer is B:
<h2>
each other</h2>
