Answer:
Dan gave his cat two treats yesterday but only one today.
Step-by-step explanation:
The past verb tense stays consistent in this sentence.
For the others:
1. Evan knew what he was doing was get him nowhere.
Get should be getting to stay in the present tense.
2. I caught a cold from my sister and then give it to my mom.
Give should be gave to stay in the past tense.
3. Kate is missing her socks, so she go back to get them.
Go should be went to stay in the past tense.
