Select the item that best completes the comparison:

chain saw is to topple as
a. bull dozer is to befuddle
b. pickax is to irk
c. fungus is to blight
d. trowel is to scan

Is the answer A. ?

No.

Please check the definitions of these words. Then try again.

Chain saw is a mechanical saw and topple means to fall or knock over.

Is it "B"

since a pickax is a handheld heavy tool and irk means to irritate?

A bulldozer may cause a tree or building to topple over.

A fungus may cause a plant to succumb to a blight.

To find the answer to this question, we need to understand the relationship between "chain saw" and "topple." The first item is a tool or instrument, and the second item is an action or result that can be achieved using that tool. So, we are looking for a similar relationship between the options.

Let's examine each option:

a. bull dozer is to befuddle
A bulldozer is a machine used for moving earth or clearing land, and befuddling means to confuse or perplex. The relationship between a bulldozer and befuddling is not the same as the relationship between a chainsaw and toppling. So, this option is unlikely to be the correct answer.

b. pickax is to irk
A pickax is a tool used for breaking up hard ground or rocks, and irk means to annoy or irritate. These items are not related in the same way as a chainsaw and toppling. Therefore, this option is not the best choice.

c. fungus is to blight
Fungus refers to a type of organism, and blight is a plant disease caused by certain types of fungi. The relationship between fungus and blight is not comparable to the relationship between a chainsaw and toppling. This option is not the correct answer.

d. trowel is to scan
A trowel is a handheld tool used for smoothing or spreading material like mortar or concrete. Scan, on the other hand, means to examine or look over quickly. There is no clear relationship between a trowel and scanning that matches the relationship between a chainsaw and toppling. Therefore, this option is also unlikely to be the correct answer.

Based on the analysis above, none of the provided options seem to be the best completion for the comparison. It is possible that there might be an error in the options or that the correct choice is not among those provided.
