Using the suffixes -ísimo, -ísima, -ísimos, -ísimas to say to say extremely/very

When we want to say "extremely" [adjective/adverb] in Spanish, we use the endings -ísimo, -ísima, -ísimos, -ísimas in Spanish.

Read and listen to these examples:

La profesora nueva es inteligentísima.
The new teacher is really intelligent.

Los conciertos de la calle son ruidosísimos.
The street concerts are the noisiest.

Las instalaciones del hotel están limpísimas.

If the adjective ends in a vowel, it is suppressed and replaced by -ísimo, -ísima, -ísimos and -ísimas.

alegre = alegrísimo
Cheerful = very cheerful

If the adjective ends in -io, then both vowels are suppressed and replaced by -ísimo, -ísima, -ísimos and -ísimas.

Hi Inma

My question is:  In the question above, why is the answer tardísima verus tardísimo.  I am trying to see what makes the answer femine instead of masculine.

I have this question as well. In the case of tú and usted commands, how do we know whether or not we should use the feminine or masculine form of the adverb? if we don't know the genders of the the subjects of the commands - how do we choose the appropriate ending?  The results seem to vary based on the test questions and the "Kwiz" questions, so I have not been able to find any context clues to answer this question.
