plz help me find the right answeres please
Did you know that just 10% of the population is left-handed? A scientist doesn’t know why some people are lefties. Genetic seems to be responsible about 25% of the time, but even identical twins, who share the same genes, can sometimes have differing dominant hands. People believe left-handed can affect many things- your performance in school, your skills at sport, and even how much money you make. There are plenty of theories about what determines which hand you write with, but a growing number of experts believe it’s random. Mixed handers – people who use both hands equally – appear to be more different from people who favor one over the other. In comparison, the difference between righties and lefties are minimal.
Which of the following statements restates the main idea of the passage?
Most scientists believe that handedness is genetic
Identical twins are more likely to have the same dominant hands
There is a lot of research about mixed - handedness
Right – or left-handedness doesn’t really affect the outcome of people lives
Which of the following details from the passage supports the main idea?
Just 10% of the population is left-handed
Many theories exist about what determines handedness
A growing number of experts believe handedness is random
Mixed -handers differ more from people who favor one hand over the other

I'll be glad to check your answers.
To find the right answer, let's analyze the passage and each statement.
The main idea of the passage is discussing handedness and its various factors. It mentions that while genetic factors may be responsible for about 25% of handedness, even identical twins can have different dominant hands. It also states that some theories suggest handedness is random. The passage concludes by stating that mixed-handers differ more from people who favor one hand over the other, and the difference between righties and lefties is minimal.
Now let's analyze each statement:
1. "Most scientists believe that handedness is genetic": This statement does not accurately restate the main idea because although genetic factors are mentioned, the passage also discusses the possibility of handedness being random and the minimal difference between righties and lefties.
2. "Identical twins are more likely to have the same dominant hands": This statement is mentioned in the passage, but it does not capture the main idea, which is a broader discussion of handedness and its factors as a whole.
3. "There is a lot of research about mixed-handedness": This statement is mentioned in the passage but is not the main idea. It is a detail supporting the main idea but does not encompass the entire passage.
4. "Right or left-handedness doesn’t really affect the outcome of people's lives": This statement accurately restates the main idea because it captures the notion that the difference between righties and lefties is minimal and the belief that handedness does not significantly impact people's lives.
Now let's analyze the details mentioned in the passage:
1. "Just 10% of the population is left-handed": This detail supports the main idea by indicating the proportion of the population that is left-handed, highlighting its relative rarity.
2. "Many theories exist about what determines handedness": This detail supports the main idea by explaining that multiple theories exist, suggesting that handedness is not easily explainable or determined.
3. "A growing number of experts believe handedness is random": This detail supports the main idea by indicating that there is a belief among experts that handedness may be random, reinforcing the notion that it is not solely determined by genetics.
4. "Mixed-handers differ more from people who favor one hand over the other": This detail supports the main idea by emphasizing the uniqueness of mixed-handers and how they differ from people who strongly prefer one hand over the other.
Based on the analysis, the correct answers are:
Restatement of the main idea: "Right – or left-handedness doesn’t really affect the outcome of people's lives."
Detail supporting the main idea: "Mixed -handers differ more from people who favor one hand over the other."
