The correct answer is C because files on the internet are stored on individual computers called servers, which host websites and deliver content when requested. The internet is not one single massive computer (option B), nor does it store files on your personal computer (option A) or on routers (option D), which simply direct traffic between servers.

The correct answer is C because Albert Einstein won the 1921 Nobel Prize in Physics specifically for his discovery of the law of the photoelectric effect, not for his theories of relativity (option A). Einstein's remarkable hair (option B) is not a scientific achievement, and he did win a Nobel Prize (option D is false).

The correct answer is B because the Motorola DynaTAC 8000X, the first commercially available mobile phone handset, was released in 1983. The 1970s saw development of car phones (not 1979 for handsets), 1991 marked the arrival of GSM digital networks (not the first handset), and 2001 is far too late.

The correct answer is C because Ray Tomlinson sent the first network email in 1971 on the ARPANET system, introducing the @ symbol format still used today. Email wasn't invented in 1961 (too early for ARPANET) or 1965, and 1988 is decades too late.

The correct answer is D because nanoparticles have all these applications: they can damage DNA through oxidative stress (A), help scientists study viral infection mechanisms by acting as delivery vectors (B), and assist in targeting tumors for drug delivery (C).

The correct answer is D because Apple has never released an iPod Vision. Apple did release the iPod Mini (A), iPod Nano (B), and iPod Shuffle (C), but iPod Vision is a fictional product name.

The correct answer is B because Douglas Engelbart invented the computer mouse in 1964 at Stanford Research Institute. Bill Gates (A) co-founded Microsoft, John Mauchly (C) co-developed ENIAC, and Robert Noyce (D) co-founded Intel.

The correct answer is B because Sir Tim Berners-Lee invented the World Wide Web in 1989 at CERN. Alan Kay (A) pioneered personal computing concepts, Jack Kilby (C) invented the integrated circuit, and Robert Noyce (D) was a co-founder of Intel.

The correct answer is D because Steve Wozniak single-handedly designed and built the Apple I computer in 1976. Bill Gates (A) co-founded Microsoft, Bill Jobs (B) is not a real person (likely a混淆 with Steve Jobs), and Steve Palmer (C) is not associated with Apple's founding.

The correct answer is B because the Hershey's chocolate bar has Hershey, Pennsylvania (town), Milton Hershey School (institution), and Hershey Company (company) all named after it. Cadbury (A) has a company but not the same scope, Mont Blanc (C) is a mountain, and Toyota (D) is a newer company.
