How can I make the following sentences using gerunds ?

I reviewed the latest development in politics.(Not Gerund Present Participle)

Some of them contain gerunds already; some you can change by copying the structure of related sentences; and others cannot be restructured to contain gerunds. Feel free to post your efforts.

Dear sir,
I Admit that I am totally unable to understand your wordings,
"They have to take the same form as the related sentences in your list".
Could you be kind enough to explain a little more so that
I and many viewers can understand.
Thanks a lot.
Yours truly,
Er.S.M.M.Hanifa

Don't worry about the other viewers. I am not getting paid for this, Mr Hanifa.

All of those sentences must be revised so that they are the same as #13 and #15.
