<h2>2. Right answer: Alegre</h2>
If your team scored a goal you must be happy, full of joy. This emotion in spanish is called alegría (happiness).
In this context you would not be agitado (troubled), enojado (angry) or furioso (furious).
When you are happy you say “estoy alegre”
Therefore the right option is B:
<h2>Alegre
</h2>
<h2>3. Right answer: Por la última vez
</h2><h2 />
<em>For the last time</em> is an expression that may be used if someone gives an ultimatum (normally when is followed by the exclamation sign) or<u> to refer about the last occasion something happened.</u>
The Spanish word <em>vez</em> (time, occasion) is feminine, hence the word <em>last</em> in spanish must be written in feminine, as well (última).
In addition, the defined article for a singular feminine noun <u>la</u> must preceed these words.
Therefore the right option is:
<h2>
Por la última vez
</h2>
