There is some force that doesn’t like walls. It causes the frozen ground to swell underneath a wall, and the wall's upper stones then topple off in the warmth of the sun. This creates gaps in the wall so big that two people could walk through them side-by-side. And then there are the hunters who take apart the wall—that’s something different. I often have to come and fix the spots where hunters haven't left a single stone in place, as they tried to flush out the rabbits that hide in the wall in order to make their barking dogs happy. No one has seen or heard these gaps in the wall being made. We just find them there in the spring, when it comes time to fix the wall. I reach out to my neighbor, who lives over a hill, and we find a day to get together and walk along the wall, fixing these gaps as we go. He walks on his side of the wall and I on mine, and we deal only with whatever rocks have fallen off the wall on our side of it. Some of them look like loaves of bread and some are round like balls, so we pray that they’ll stay in place, balanced on top of the wall, saying: "Don’t move until we’re gone!" Our fingers get chafed from picking up the rocks. It’s just another outside activity, each of us on our side of the wall, nothing more.
There’s no need for a wall to be there. On my neighbor’s side of the wall, there’s nothing but pine trees; my side is an apple orchard. It’s not like my apple trees are going to cross the wall and eat his pine cones, I say to him. But he just responds, "Good fences are necessary to have good neighbors." Since it’s spring and I feel mischievous, I wonder if I could make my neighbor ask himself: "Why are they necessary? Isn’t that only true if you’re trying to keep your neighbor’s cows out of your fields? There aren’t any cows here. If I were to build a wall, I’d want to know what I was keeping in and what I was keeping out, and who was going to be offended by this. There is some force that doesn’t love a wall, that wants to pull it down.” I could propose that Elves are responsible for the gaps in the wall, but it’s not exactly Elves, and, anyway, I want my neighbor to figure it out on his own. I see him, lifting up stones, grasping them firmly by the top, in each hand, like an ancient warrior. He moves in a deep darkness—not just the darkness of the woods or the trees above. He does not want to think beyond his set idea about the world, and he likes having articulated this idea so clearly. So he says it again: “Good fences are necessary to have good neighbors.”
The words that should fill in the blanks are "simulation" and "sample space." In that case, the full sentence would be:
"You can use the experimental probability based on observation or simulation to set up a sample space and use it to predict a value."
We can arrive at this answer because:
The sentence above refers to the use of experimental probability, which is a system that allows predictions and hypotheses to be made about a given subject.
In this type of system, the use of simulations is very common, since these simulations allow the probability of something happening to be studied.
The sample space is also widely used, as it allows a set of data, which can be used in the future, to be predicted and studied.
In this case, we can say that the experimentalprobability is performed with the help of other elements to be effective.

After reading the article, I still believe that feeding the birds is a good idea.
Explanation:
The article shows that installing feeders that provide food to birds is a good action, but that it may not satisfy the real needs of birds, as each of them has a different nutritional need, and feeding them can expose them to dangers that they would not have in the urban environment.
However, even in the face of the negative points, I believe that installing bird feeders remains a good idea, since, with increasingly strong deforestation, birds have been experiencing difficult situations to find food, water and sometimes even shelter. Thus, being able to help them at least by feeding them is a noble and commendable step.
