They <u>take</u> just as long to cook dinner as i do.
What do you want us to do with this phrase i might be able to answer in comments
Answer: carry on
Explanation: persevere means to continue and not give up. Giving in is the exact opposite of not giving up. Cooperate means to work with someone else which is not a synonym of not giving up. Adjust means to cope and change to something new and different. Therefore carry on is the best fit.
