Unfortunately, you forgot to attach the scores shown in the back-to-back stem-and-leaf display. So we do not know what the numbers are and we do not have any reference at all
What we can do to help you is to comment on the following general terms.
There have been previous and similar experiments or projects like this in other schools in America. These results suggest that the new activities are better because extra or special reading comprehension programs better prepare students to understand what they are reading and comprehend more than basic ideas of the text.

What don’t you understand
Answer:78 guests
Step-by-step explanation:
understanding the problem
the furniture is set up for the reunion and we need to determine how many guests are expected
devising a plan
the furniture for guests = chairs
steps
determine the number of tables as there are 6 chairs to each table
what is the unknown?
number of tables and number of chairs
what are the data?
364 furniture legs
tables sit 6 chairs each
tables have 4 legs
each chair has 4 legs
which letter should determine the unknown?
a= tables
b= chairs
what is the condition linking the letters
a*6=b
(a+b)*4=364
is the condition sufficient to determining the unknown?
364/4= a+b
91= a + b
a * 6 = b
b/6 = a
91- b = a
91 = (91-b) + a
(91-b) * 6 = b
b/6=91-b
b= 6*91 - 6b
b = 546 - 6b
b + 6b = 546
7b = 546
b = 546 / 7
answer
b = 78 guests = chairs
test
a*6 = 78
a= 78/6 = 13 tables
(a + 78) * 4 = 364
(13+78)*4 = 364
91*4= 364 correct
364/4= a+ 78
91 = a + 78
91 - 78 = a = 13 tables
