1) Although the truth has yet to be established, I believe Ferdinand Magellan was slain by a poison arrow rather than Lapu-Lapu. 

2) The atmosphere and ecological niches are constrained around the planet since it is a close system. War is pointless since it causes so much pain, not to mention the gas, chemicals, and radioactive waste that it generates. All of these waste products are suffocating the planet, which will eventually harm us all. It's baffling and ruthless. But I don't believe it's "useless."

3) Russia has begun a catastrophic air, land, and sea war on Ukraine, a European democracy with 44 million people, and its forces are on the outskirts of Kyiv, the capital.

For months, President Vladimir Putin claimed that he would invade Ukraine, but then he ripped up a peace agreement and sent troops across the country's north, east, and south borders.

As the death toll rises, he is accused of ruining Europe's calm. What happens next might put the continent's whole security system at jeopardy.

4) There are 33 phonemes in Tagalog, with 19 consonants and 14 vowels. The syllable pattern is basic, with Cr only appearing in borrowed words like trak "truck" or sombréro "hat."

(I'm not sure about my answer, therefore it could be incorrect; you should want to do some research since I'm not too knowledgeable about history.)
