Which statement best describes the difference between science and engineering?

Science builds things; engineering explains how they work Science seeks to understand nature; engineering applies knowledge to build solutions Engineering and science are the same discipline with different names Science uses experiments; engineering only uses mathematics

A civil engineer is most likely responsible for which of the following projects?

Designing an electric motor for an electric vehicle Developing a new pharmaceutical compound Designing a highway interchange and drainage system Designing a microprocessor circuit

The Roman aqueducts transported water over distances of up to 90 km without any pumps. What engineering principle made this possible?

High-pressure steam pumps installed at intervals A carefully maintained downward slope using gravity to drive the flow Underground heating that made water expand and rise Animals pulling water-lifting wheels at relay stations

Which branch of engineering would be most involved in designing a refinery that converts crude oil into gasoline?

The Brooklyn Bridge, completed in 1883, was an engineering milestone primarily because it was the first large-scale use of which material?

Reinforced concrete in a major bridge deck Aluminium alloy for structural beams Steel wire cables for a suspension bridge Pre-stressed concrete piers

Technology is best described as:

The study of natural phenomena using observation The tools, systems, and products created through engineering and science A branch of mathematics dealing with computation The process of turning a scientific theory into a law

An electrical engineer is designing a solar-powered charging station. Which day-to-day task would she most likely perform?

Testing the chemical composition of the solar panel glass Calculating the circuit's load requirements and selecting appropriate components Pouring the concrete foundation for the station Writing advertising copy for the product launch

The Apollo 11 moon landing in 1969 required contributions from multiple engineering branches. Which engineering discipline was primarily responsible for designing the Saturn V rocket engines?

Civil engineering Chemical engineering alone Mechanical and aerospace engineering Electrical engineering alone

The Hoover Dam, completed in 1936, generates electricity from flowing water. What engineering achievement does it best represent?

Pure mechanical engineering to spin turbine blades Chemical engineering to treat the water supply Civil and electrical engineering working together to create hydroelectric power infrastructure Software engineering to automate the floodgates

A mechanical engineer is most likely to spend their day doing which of the following?

Writing software code for a mobile app Analysing stress on a gear assembly using computer simulation Designing a water treatment chemical dosing schedule Surveying land elevation for a road project

Engineering is often described as 'structured problem-solving'. What does 'structured' mean in this context?

Using steel and concrete to build rigid structures Working only within government regulations Following a systematic process of defining, testing, and refining solutions Ensuring that all designs are symmetrical

Which of the four main engineering branches would most likely be involved in designing the sensors and control systems for a self-driving car?
