Hey there,
When we got Gigi as a puppy, it was vital that we get her shots so she didn’t get sick. Now that she’s a year old, it’s [tex]\boxed{necessary}[/tex] that we take her to the vet for her annual checkup and update on her shots. She needs them so we can renew her license.
Your correct answer would be (necessary) because the word critical synonym would be impossible.
Hope this helps.
