Question

complete the text with the transition that best connects the claim to the evidence that supports it.
paper bags are not necessarily more environmentally friendly than plastic bags. ______, consider a uk environment agency study that found that a paper bag has to be used three times before it can be said to have a lower impact on global warming than a single - use plastic bag.
nonetheless
admittedly
by way of illustration

Explanation:

The transition needs to introduce supporting evidence for the claim that paper bags are not more eco-friendly. "By way of illustration" is used to provide an example that proves the preceding statement, which matches the need to link the claim to the UK Environment Agency study as supporting evidence. "Nonetheless" and "Admittedly" introduce contrast or concessions, which do not fit here.

Answer:

By way of illustration
