I think the greatest invention was electricity, because there are many things that facilitate our life, for instance home appliances, technology in manufacturing, research laboratories and conservation of food.

Hola Lizbeth, no está mal. "Light" - la luz; "electricity" - la electricidad. ManufacturING es la actividad de fabricar. "Investigation" es lo que hacen la policia con un crimen. "Research" - la investigación - lo que hacen los científicos. Sigue practicando. Saludos desde España, Simón.
