final hook I can't find the grammar mistakes

In the twenty-first century, many countries will become increasingly dependent on the generation of children, and this includes immigrant children. These children will have a significant impact on their nation's social and economic future when they grow up. A country’s future prosperity depends on a child it's children. So investing in the educational development of all the nation's children, is to invest in a brighter future. We need to pay more attention to solve the problem of learning a new language for immigrant children. Increasing efforts to enhance their language skill is critical. It is not only for these children themselves, but for our nation.

Dominican Republic a country to holiday in

If i have to talk about a Dominican's place to visit and the best place to visit in the Dominican Republic to take nice pictures, the first thing that I get in my mind, its to talk about "los tres ojos national park". It’s a limestone cave located in the mirador del este park, in the eastern part of Santo Domingo, the three eyes as it's better known. It's a lake which is divided naturally into three parts; there is also a separate lake, which can be observed from the outside without actually entering into the caves .

The site was created centuries ago as a result of tectonic fractures when underground caves collapsed, forming a bowl-shaped depression which subsequently filled with water. The depth of the lake so far remains unknown. Initially, the cave was inhabited by (Taínos) who were the first inhabitants of the Dominican Republic.

The three lakes are called "Aguas Azufradas" (discovered in 1916), "The Nevera" and "El Lago de las Mujeres" Some of the lakes also have openings on the outside. The fauna is also very varied and includes fish, bats, and turtles and more.. , the vegetation is also lush and abundant.

This is me.
