Analysis of tree bark showed something about chemical insecticides. It did not show 'chemical insecticides'. C, D and E are out.

From A and B

A. that chemical insecticides have often spread thousands of miles from where they were originally used. Correct choice

B. that chemical insecticides have spread, often thousands of miles from their original use.'have spread, often' has different meaning from 'have often spread'

in b,
insecticides have spread thoussand of miles from their orriginal use

is not logic.
from should be follow by a place, where, not by an abstract noun like "use". using our common sense of this world, we realize the illogicness.

Is it always necessary that 'that' comes after verb 'shows' ?

I know that 'that' should come after reporting verbs but like in this sentence is it necessary ?

An analysis of tree bark all over the globe shows that chemical insecticides have often spread thousands of miles from where they were originally used.

Issues: Modifier | Meaning

Analysis:
1. First split is around "globe shows that chemical.." vs "globe shows chemical..". Without "that", the second version becomes a fragment, eliminating (C), (D) and (E).
2. Between (A) and (B), (B) has issues as highlighted below

A. that chemical insecticides have often spread thousands of miles from where they were originally used

B. that chemical insecticides have spread, often thousands of miles from their original use
- "their original use" is not a place and saying thousands of miles from their original use is illogical.

C. chemical insecticides, having often spread thousands of miles from where they were used originally - fragment

D. chemical insecticides, often spreading thousands of miles from where their original use - fragment

E. chemical insecticides, often spreading thousands of miles from where they were originally used - fragment

Dear colleagues,
I absolutely agree that questions b-e are wrong and I also have chosen A.

BUT, why can we use "have + often + spread" ?
I think that "often" is a market of "present simple" and for my ear it is weird to hear have + often construction.

@mikemcgarry,@egmat

Though I got this question correct. I need some clarity on the official answer of this question-

Official Solution says -"To express the intended meaning, shows can be followed by a clause beginning with that. Another option would be to use the special clause type show + noun phrase + ing verb form, such as show chemical insecticides spreading many miles—but there should be no pause in the middle of a construction of this latter type. If there is such a pause, then chemical insecticides becomes the direct object of show, and the following verb-ing phrase is an awkward attempt at a modifier of this object".
