Question

Before 1990, which technologies were available to internet users?

A) File sharing
B) Online shopping
C) Streaming video
D) Cloud computing

Answer 1

A. File Sharing was available to internet users before 1990.

Answer 2

the correct answer is D: Cloud computing

Step-by-step explanation:

Among the options:

A) File sharing emerged in the late 1990s

B) Online shopping really took off in the late 1990s

C) Streaming video emerged in the mid to late 2000s

Only D, cloud computing, emerged around 2006, after the specified period of "before 1990".

So while email, bulletin board systems, and other technologies were available before 1990, cloud computing - where software and data are accessed over the internet - did not emerge until around 2006.

Therefore, the answer is D: Cloud computing.

The other options - file sharing, online shopping, and streaming video - can be eliminated because the passage states they emerged after 1990, not before 1990 as the question specifies.
