  • Is it a bad idea to get braces off early?

    My teeth were never that bad in the first place. They were a little bit crooked. They all straightened out in about 2 months. I've had them on for a year now. The orthondontist says I will have them on for at least another year. I can't have them on. I've been trying out for a big show and I was offered a lead role if my braces were taken off. The show starts in January and I have to make a decision. A lead in this show would give me so many opportunities and really start my career. What the heck do I do?

  • Help me with my conclusion for my World War 1?

    Wrote an essay about World War 1. It's all done I'm just having a very difficult time writing the conclusion. Here is my thesis, could you help me writing my essay?

    European nations succeeded in military dominance, creating alliances, imperialism, and

    nationalistic extremes, which were the four building-blocks of World War 1. Nationalism rose

    among European countries as they competed to have the best and the most of everything; there

    was competition over materials, markets, and land which lead to many disputes. Nations

    competed fiercely for colonies in Africa and Asia, the quest for colonies brought a sense of

    rivalry and mistrust among nations. Countries glorified military power and kept armies prepared

    for war; countries increased their spending on weapons and created bigger armies. Nations

    created systems of alliances, and proclaimed to be strict enemies against opposing alliances.

    These four actions would be the foundation of a world war, that’d only bring blood, brutality,

    and utter destruction to many lives.

  • Can you proofread my intro to my World War 1 essay?

    Can you proofread my introduction paragraph which is about the causes of World War 1? Please tell if me I can change anything to make it sound better.

    European nations succeeded in military dominance, creating

    alliances, imperialism, and nationalistic extremes; to which were the four building-blocks of World War 1. Militarism was heavily enforced; countries increased their spending on weapons, created bigger armies that threatened others. Countries created systems of alliances, and proclaimed to be strict enemies against opposing alliances. Nations competed fiercely for colonies in Africa and Asia, the quest for colonies brought a sense of rivalry and mistrust among nations. Nationalism rose among countries as they competed to have the best and the most of everything; there was competition over materials, markets, and land which lead to many disputes.
