What common theme connects the two initial images shown by the speaker?

• Water pollution and waste disposal

• The beauty of marine life

• The complexity of natural systems

• The challenges of deep-sea exploration

To illustrate the vast amount of plastic on the ocean's surface, the speaker compares it to stacking 2-liter bottles. How far would these bottles reach?

• To the moon and back once

• To the moon and back twice

• To Mars and back

• Around the Earth's equator

What was the primary cause of death for the young whale found on the shores of the Northern Netherlands?

• Old age

• Intestinal blockage

• A fishing net

• A bacterial infection

The speaker suggests that plastic we dispose of can eventually end up in our food. What term does he use to describe this cycle?

• The food chain effect

• The vicious karmic cycle

• The marine ecosystem imbalance

• The plastic consumption loop

What everyday observation inspired the speaker's idea for the Ervis ocean cleaner?

• The movement of ocean currents

• The swirling water in a sink drain

• The way fish consume food

• The design of a football

What inspired the speaker's initial design for ERVIS?

• A dream about a clean ocean.

• A science fiction spaceship.

• A common household item.

• An animal from the ocean.

What materials were used to construct the first prototype of ERVIS?

• Recycled plastic bottles and fishing nets.

• An inflatable tube, straws, and cardboard.

• Metal sheets and advanced robotics.

• Wood, fabric, and glue.

Why did the speaker decide to redesign the initial circular shape of ERVIS?

• It was too difficult to build.

• It was not aesthetically pleasing.

• It was not efficient for its purpose.

• It could not hold enough waste.

What type of energy source was considered for the redesigned ERVIS to avoid pollution?

• Diesel and gasoline.

• Nuclear power.

• Renewable and clean energy sources.

• Coal and natural gas.

What are the three main functions the speaker envisions for ERVIS?

• Transporting goods, mapping oceans, and studying marine life.

• Cleaning existing waste, analyzing collected data, and stopping pollution at its source.

• Creating artificial reefs, generating electricity, and monitoring weather patterns.

• Exploring deep-sea trenches, discovering new species, and building underwater cities.
