<p>This references Question 50 of English Practice Section 3 (p.169) in my Princeton 1,296 ACT book.</p>
<p>Anderson's model was different from todays models, though, because it was hand-activated by a lever from inside the car.
* "todays models," is underlined.</p>
<p>F. NO CHANGE
G. today's models,
H. todays' models
J. today's models</p>
<p>I picked choice J, but the correct answer is G. Can you explain why a comma is need after "models"? It seems awkward to pause there if you read it out loud.</p>
<p>Thank you so much!</p>
