Answer:
El Cálculo Diferencial se origina en el siglo XVII al realizar estudios sobre el movimiento, es decir, al estudiar la velocidad de los cuerpos al caer al vacío ya que cambia de un momento a otro; la velocidad en cada instante debe calcularse teniendo en cuenta la distancia que recorre en un tiempo infinitesimalmente

The ice trade
Before refrigerators existed, there was ice. Without ice, people couldn't keep food cold, which meant they were limited to food that didn't spoil or food grown near where they lived. A businessman named Frederic Tudor understood that consumers, including food producers, wanted to keep supplies fresh. In 1806, he founded a company that shipped ice from frozen lakes, ponds, and streams to other parts of the United States and the world. Customers were able to keep food for longer and more safely. The ice allowed farmers to send food further and fishermen to store their catch. The ice trade forever changed the health of Americans by making it easier to preserve food.
Passage 2
The fridge
Although the first refrigerator for home use was available in 1913, it wasn't until 1927 that refrigerators looked the way they do today. Between 1913 and 1927, various inventors toyed with different ways to build the refrigerator. Some versions had many parts that had to be placed in different rooms of a house. Other versions came as a single unit, but they were big and expensive. General Electric was the first company to make a refrigerator, the "Monitor Top", which was self contained and affordable. More Americans were able to keep fresh food in their homes, improving health and increasing the variety of foods they ate. However, this model used dangerous chemicals. In the 1930s, newer and safer chemicals were used in refrigerators, making them the essential appliance we have today. What detail is mentioned in both passages?

Actualmente, casi un 40% de todas las especies de animales están encontrándose (present progressive) en peligro de extinción. El término peligro de extinción se le acuña a todos aquellos animales pertenecientes a una especie que corren el riesgo de estar desapareciendo (present progressive) del planeta tierra. Algunos de los animales en peligro de extinción son:
- Gorila de montaña
- Oso Polar
- Oso Panda
- Tigre sumatra
- Chimpancé
Para evitar la extinción de estos animales se debe realizar lo siguiente
- Prohibir la caza, debido a que esta es una de las razones que tienen más peso en la posible desaparición de algunas especies.
- Evitar la deforestación de bosques es otra de las medidas que se debe tomar.
- Evitar la contaminación del medio ambiente. La contaminación tiene un peso muy importante en el calentamiento global, que ha afectado directamente el habitat de los osos polares
- Promover el reciclaje ayudaría a evitar la tala de árbol.
Algunos hechos importantes:
- 40% de los anfibios se encuentran en peligro de extinción
- 20% de los mamíferos se encuentran en peligro de extinción
- 14% de las aves se encuentran en peligro de extinción
- 30% de los tiburones y rayas se encuentran en peligro de extinción
