Step-by-step explanation:

Blank C :

Given total = 68

No. of TV news = 13

Therefore, in Internet it would be = Total - TV news

= 68 - 13 = 55 (ans)

Blank D :

No. of Internet news in 7th grade = 55

No. of Internet news in 8th grade = 64

Hence, total Internet base news = 64 + 55 = 119 (ans)

Blank B :

All total = 138

Internet news total = 119

Hence, TV news total = All total - Internet news

= 138 - 119 = 19 (ans)

Blank A :

No. of TV news in 7th grade = 13

Total news in TV = 19

Therefore, no. of TV news in 8th grade = 19 - 13 = 6(ans)

Blank E :

All total = 138

Total of 7th grade news = 68

Hence, total of 8th grade news = 138 - 68

= 70 (ans)
