Answering with word and word sequence.
This quiz contains examples of specifications of correct answers in
the form of so-called non-numbers, i. e. character strings representing
a scalar (or single) value, which is not a number.
Question number
1
.
The specification of a correct answer is:
a12B3f
The only correct answer is:
a12B3f
with any number of preceding and trailing blanks.
The value shown is interpreted as a non-number, i. e. a sequence of characters beginning with neither a digit nor a minus-sign.
A non-number normally begins with a letter but certain special characters are also permitted in the beginning of a non-number.
Certain special characters are used for special purposes and are therefore not permitted in non-numbers.
Question number
2

The specification of a correct answer is:
I have One dog

Specifications and answers are case sensitive.

The period (or full stop) indicates that the answer is any sequence
of characters starting with the character string before the period
excluding characters not permitted in non-numbers.
Question number
4

A correct answer could be:
