Q: The popliteal lymph nodes, small in size and some six or seven in number, are embedded in the fat contained in the popliteal fossa, sometimes referred to as the 'knee pit'. One lies immediately beneath the popliteal fascia, near the terminal part of the small saphenous vein, and drains the region from which this vein derives its tributaries, such as superficial regions of the posterolateral aspect of the leg and the plantar aspect of the foot.
Can we conclude that is there a lymph node behind the knee?
OPTIONS:
- no
- yes
A: yes

Q: The phase velocity of an electromagnetic wave, when traveling through a medium, can routinely exceed c, the vacuum velocity of light. For example, this occurs in most glasses at X-ray frequencies. However, the phase velocity of a wave corresponds to the propagation speed of a theoretical single-frequency (purely monochromatic) component of the wave at that frequency. Such a wave component must be infinite in extent and of constant amplitude (otherwise it is not truly monochromatic), and so cannot convey any information. Thus a phase velocity above c does not imply the propagation of signals with a velocity above c.
Can we conclude that can phase velocity be greater than speed of light?
OPTIONS:
- no
- yes
A: yes

Q: At club level, Messi and Ronaldo represented rivals FC Barcelona and Real Madrid C.F., the two players facing each other at least twice every season in the world's most popular regular-season club game, El Clasico (among the most viewed annual sporting events), until Ronaldo's transfer to Italian club Juventus F.C. in 2018. Off the field, they are the face of two rival sportswear manufacturers, Messi of Adidas and Ronaldo of Nike, which are also the kit suppliers of their national teams and the opposite for their clubs. The two highest paid players in football, Ronaldo and Messi are among the world's best paid sports' stars in combined income from salaries, bonuses and off-field earnings. In 2016, Ronaldo was first on Forbes list of the best paid athletes, earning $88 million, with Messi being second at $81.4 million. They have the two biggest social media followings in the world among sportspeople with a combined 211 million Facebook fans, with Ronaldo having 122 million and Messi having 89 million. With a combined Facebook, Instagram and Twitter, Ronaldo has 321 million to be the most famous celebrity on social media and Messi has 181 million excluding Twitter.
Can we conclude that have messi and ronaldo ever played against each other?
OPTIONS:
- no
- yes
A:
yes
