Here is a question about this article: Among the other phyla, the Ctenophora and the Cnidaria, which includes sea anemones, corals, and jellyfish, are radially symmetric and have digestive chambers with a single opening, which serves as both the mouth and the anus. Both have distinct tissues, but they are not organized into organs. There are only two main germ layers, the ectoderm and endoderm, with only scattered cells between them. As such, these animals are sometimes called diploblastic. The tiny placozoans are similar, but they do not have a permanent digestive chamber.
What is the answer to this question: What differentiates placozoans from the ctenophora and the cnidaria?
****
So... they do not have a permanent digestive chamber


Here is a question about this article: Far from being a mere "stopgap" pope, to great excitement, John XXIII called for an ecumenical council fewer than ninety years after the First Vatican Council (Vatican I's predecessor, the Council of Trent, had been held in the 16th century). This decision was announced on 29 January 1959 at the Basilica of Saint Paul Outside the Walls. Cardinal Giovanni Battista Montini, who later became Pope Paul VI, remarked to Giulio Bevilacqua that "this holy old boy doesn't realise what a hornet's nest he's stirring up". From the Second Vatican Council came changes that reshaped the face of Catholicism: a comprehensively revised liturgy, a stronger emphasis on ecumenism, and a new approach to the world.
What is the answer to this question: Who did Cardinal Giovanni Battista Montini later become?
****
So... Pope Paul VI


Here is a question about this article: USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
What is the answer to this question: What was designed to standardize the connection of computer peripherals?

So...
