PLEASE HELP ME please answer those three questions please As the teacher brought the class back from the washroom, he noticed that Alvin and Elijah were nowhere to be seen. He asked the class, "Has anyone seen Alvin or Elijah?" Most of the students confirmed that they had not seen them, except for Rodney, who remained silent while tapping his foot on the floor anxiously. The teacher noticed this. "Rodney, do you happen to know where your best buddies Alvin and Elijah went?" Rodney looked away and said, "Nah, I haven't seen them." The teacher notified the office of the missing students. An announcement was made over the PA system and a few minutes later, Alvin and Elijah returned to class. Both of them were very sweaty and Elijah was carrying a basketball. "Sorry we took so long. We had to use the bathroom," said Elijah. "Yeah," chimed in Alvin, "it took longer than we thought."

What were Alvin and Elijah doing while they were gone? How do you know this?

Why was Rodney acting so strangely?

How do you know this? Will the teacher believe Alvin and Elijah's story? How do you know this?
