Question

Human beings___odd,if they had four hands Use the suitable form of the verb 'look'.

Answer 1

Human beings would look odd, if they had four hands.

Linking verbs connect the subject with a word that gives information about the subject, such as a condition or relationship. They do not show any action. They link the subject with the rest of the sentence.

Look, seem, sound, smell, remain, stay, turn, taste, appear, feel , become, grow, am, is, are, was, were, being, been are linking verbs.

Answer 2

The answer of your question is “would look”

So the full answer will be like that “Human beings would look odd, if they had four hands”.  The sentence is representing that the something is being assumed. Here the linking verb which represent the action by the linking the words will come . This is much like the “are” “was” but as the assumption is being made here so the “would look” will be the answer here.
