Here are the correct words to fill in the blanks, based on the root words provided. I have changed the form of the words (using prefixes like *un-*, *in-*, *dis-* or suffixes like *-able*, *-ing*, *-ed*) to fit the grammar of each sentence.
1.
understandable
* (From *understand*: We need an adjective to describe the reaction. Adding *-able* makes it "capable of being understood.")
2.
adjustable
* (From *adjust*: We need an adjective to describe the seat belts. Adding *-able* means they can be adjusted.)
3.
disfigured
* (From *figure*: The face was damaged. The prefix *dis-* and suffix *-ed* create the word for having one's appearance spoiled.)
4.
uninterested
* (From *interest*: The students don't pay attention, so they lack interest. *Uninterested* means not caring about something.)
5.
excruciatingly
* (From *excruciate*: We need an adverb to describe how painful it was. Adding *-ly* turns the adjective *excruciating* into an adverb.)
6.
inextinguishable
* (From *extinguish*: Their love could not be put out. *In-* means "not," and *-able* means "capable of." So, "not capable of being extinguished.")
7.
inalienable
* (From *alien*: A right that cannot be taken away or transferred. *In-* means "not," making it "not able to be alienated/taken.")
8.
exceedingly;
unwind
* (From *exceed*: We need an adverb meaning "very much." *Exceedingly* fits here. From *wind*: To relax is to *unwind*.)
9.
competence
* (From *compete*: We need a noun for the skill of using language. *Competence* means the ability to do something successfully.)
10.
irrevocable
* (From *revoke*: Laws/freedoms that cannot be taken back. *Ir-* means "not," and *-able* means "capable of." So, "not capable of being revoked.")
11.
contemplative
* (From *contemplate*: A mood where someone is thinking deeply. The suffix *-ive* turns the verb into an adjective describing the mood.)
12.
consumer;
acquisition
* (From *consume*: A society focused on buying things is a *consumer* society. From *acquire*: The act of getting goods is *acquisition*.)
