An essay about your favorite footwear should analyze the ideas of why you enjoy that specific footwear. Mostly you should analyze the looks and the feel of the footwear, meaning you should discuss why you feel comfortable in the footwear of your choice.
A: Mom and her sisters have decided to go on a trip together
for B it should be: His uncles and my brother were going on a camping trip
for C: the wording is just funky.
for D it should be: Both Natalia and Mike have invited us over
Hopefully this helps and good luck.
False because you can't always be feeling very positive of what your saying all the times.
Like they say "Nobody's perfect" :)
