Answer:
1. seniority
2. sanitation
3. facilities
4. instrument
5. expressway
Step-by-step explanation:
The above are the correct answers that fit into each sentence.
In number 1, seniority is correct because the dad was stating that he has seniority over his son.
In no. 2, sanitation is correct because the individual was asking of sanitation laws.
In no. 3, facilities is correct because it fits into the statement that Grandma thinks a place is nicer when the facilities in that place are situated outside.
In no. 4, the dad referred to the toothbrush as an instrument. In no. 5, expressway is the correct option. The sentences like "how many miles long it was" shows that expressway is the correct answer in that context.
