Question

we have no experience regarding sea-turtles, so first of all we undertook a study of turtles. ( correct the error)

Answer 1

Answer:

We had no experience regarding sea-turtles, so first of all we undertook a study of turtles.

Explanation:

We have no experience regarding sea-turtles, so first of all we undertook a study of turtles.

Above was the statement given in the question.

If you read the question carefully, you'll find that both the words "have" and "undertook" exist in the statement.

Now, "have" is in present tense while "undertook" is in past tense.

So the error has to be one of those words.

The sentence can either be in present or past tense in this particular case.  The tone of the statement suggests that it should in fact, be written in past tense.

Hence, the word "have" is incorrect and therefore should be changed to "had".

Hope this helps!!
