Mikayla placed the dough on her right fist and then spins it into the air, trying to mimic the chef. What change should be made in sentence 3

This question is missing the options. I've found the complete question online. It is the following:

What change should be made in sentence 3? (Mikayla placed the dough on her right hand and then spins it into the air, trying to mimic the chef.)

A. Insert a comma after "fist".

B. Change "then" to "than".

C. Change "spins" to "spun".

D. Change "it" to "them".

The change that should be made in sentence 3 is:

C. Change "spins" to "spun".

Explanation:

The sentence "Mikayla placed the dough on her right hand and then spins it into the air, trying to mimic the chef" is incorrect for only one reason - the shift in verb tenses. The sentence begins with a verb in the simple past and, all of a sudden, changes to the simple present. It is clear that this is a sequence of actions that took place in the past, one after the other, so the shift is inappropriate in this case. To correct it, we must change the verb in the present form (spins) to the past form (spun):

Mikayla placed the dough on her right hand and then spun it into the air, trying to mimic the chef.

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
