The potato famine in ireland in the mid 1800's can be considered a "pull" factor that caused people to migrate (come to) to the u. s. question 1 options: true false

True because it caused people to migrate to the u.s  if there wasn't a potato famine than they wouldn't have to move.

Yes it does it sure does me later

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
