which of the following meta-search engines was an attempt at natural language inquires

a.dogpile
b.internet sleuth
c.metacrawler
d.ask

my answer is d

Probably yes, but all of them act that way.

Your answer is correct. The meta-search engine that was an attempt at natural language inquiries is "d. ask."

To arrive at this answer, I'll explain each option briefly:

a. Dogpile: Dogpile is a meta-search engine that gathers results from multiple search engines. However, it does not focus on natural language inquiries.

b. Internet Sleuth: Internet Sleuth is not a well-known meta-search engine and is not known for its focus on natural language inquiries.

c. Metacrawler: Metacrawler is another meta-search engine that provides results from various search engines but does not prioritize natural language inquiries.

d. Ask: Ask.com, also known as Ask Jeeves, is a meta-search engine that was initially designed to accept natural language queries, which means users could ask questions in plain English instead of using specific keywords. However, it has transitioned into a more traditional search engine over the years.

Therefore, "d. ask" is the correct choice as it was an attempt at natural language inquiries.
